5 1 INTRODUCTION The Sesam TM May 2017 Release is the collection of Sesam programs as of 5 May There are many significant updates on several programs as compared to the previous release (December 2015). The continuous investments in Sesam lead to new and improved products that help our customers become more efficient. They also get higher data quality during import from other sources as well as easier data sharing with other Sesam customers. This release includes additional functionality for all the industry segments supported by Sesam, including jacket analysis, floater analysis (offshore and ship specific), offshore wind turbine foundations, riser & pipeline design and marine operations. The amount of new functionality is a proof that we invest heavily based on listening to customer needs says Ole Jan Nekstad, Product Director Sesam. Your feedback is important to us and the above improvements are a result of such. If you have any suggestions, questions or feedback please send an to: software.support@dnvgl.com or contact one of our local offices. We thank you for your continuous support of Sesam. In this release document, you can read about the major new features and how to upgrade models created in previous versions. Detailed update information for each Sesam program can be found on the Customer Portal. The three most significant updates during the last year have been: - Member code checking based on frequency domain results can now be done in GeniE. This means that structural analysis results from e.g. a hydrodynamic analysis in HydroD can be imported and used for member code checking in GeniE. - Significantly reducing the analysis time for jacket fatigue analysis. Dynamic spectral fatigue is now much easier because of faster analysis time and automatic detection of steady state for use in fatigue computation. In most cases, we see that the elapsed computational time decreases with a factor of 30 or more typically from 11 hours to 20 minutes. - Hydrodynamic stability analysis greatly enhanced. The new stability analysis is based on a new modern user interface and a more robust solver. The reporting functions are also much more flexible and HydroD can now produce the so-called stability booklet. RELEASE DOCUMENT The Sesam May 2017 Release Page 3

6 2 HIGHLIGHTS OF THE SESAM MAY 2017 RELEASE Sesam has been a modular system since the first release in This has proven to be a success since our customers can pick the functionality they need. The modularity also eases replacing outdated program modules with new and modern software, again to the benefit of our customers. To ease the understanding of the Sesam offerings we have made some packages by grouping together relevant Sesam modules. These are described in the following and include the highlights for this release. More details may also be found in Chapter 5. We are also very pleased to announce that for GeniE and HydroD5 (for stability analysis) we have introduced a database file format (called GNX and HYDX) independent of program versions. Using the GNX/HYDX file format ensures significantly less elapsed time needed for large modelling operations and meshing. Furthermore, the GNX/HYDX file format is independent of newer GeniE/HydroD5 versions, meaning that when upgrading to a newer version of GeniE or HydroD5 there is no need for manual export and import of typically js, XML or GNX as it can be directly opened in a newer version. 2.1 Sesam Manager The new version of Sesam Manager will ease the work to do dynamic spectral fatigue of jackets. It comes with a pre-defined template for analysis set-up for dynamic analysis including fatigue analysis. The template will help you to Compute wave loads by stepping through waves one cycle is computed for each direction. Previously it was necessary to know (or to guess) how many cycles that were needed to reach steady state condition Run dynamic direct time integration repeating wave cycle until steady state detected. There is no need to manually check when a steady state has been reached. The start of steady state condition may be different from one direction to another direction. It is easy to verify from 2D plots that steady state has been reached e.g. 2D plots of base shear forces Create a result file with one cycle for each wave load after steady state has been reached. The result file is automatically set up for use in the fatigue analysis. Hence there is no need for the user to manually define start and stop positions to define the stress cycles to be used in fatigue analysis RELEASE DOCUMENT The Sesam May 2017 Release Page 4

7 2.2 Sesam Fixed Structures Package This package includes all Sesam programs needed for structural analysis during design, transportation, operation or decommissioning. Since the previous Sesam 2015 release (December 2015) there have been two GeniE releases, including supporting programs (Wajac, Splice, Sestra, Framework and Xtract). The main features and benefits of these releases are listed in the following. New features in the Floating Structure (see next chapter) may also be relevant for fixed structures. The effect of warping torsion has now been added to the member code checking of open profiles. The user may now select case 3, 4 or 7 from the AISC guidebook to be part of the member code check. Previously, this was not supported by GeniE and led to extra manual calculations for the designer. Compared with other commercial programs, we believe GeniE is the only one that supports three torsion models from the AISC guidebook. Partial update/refresh of buckling capacity models. The new feature closes the design iteration loop since it is now possible to insert new members after a code check and automatically update the code check model and keep what is unchanged. The user benefit is that it is no longer necessary to make the code check model all over again, but keep what is not affected by the new, added structure. Improved reporting of pile capacity and soil results for use in design decisions. Pile capacity curves can now easily be made to determine the pile penetration depth. Furthermore, there is an automatic scanning to find the Maximum Axial Capacity for Critical Load Cases and Factor of Safety. Another important functionality, that can save users up to 70% in their work to convert data from geotechnical reports to analytical format, is the in-built utility tool for soil data conversion. It will allow for import of soil data in a spread-sheet format, allowing for review and modification if needed, before integration with the rest of the structural model. The example above shows a typical soil data report in Excel format. The data has been imported into the utility tool for soil conversion to Sesam format. The user may verify the data (graphically and tabular) and modify if needed before exporting it for use in GeniE. The figure to the right shows that the soil data has been imported seamlessly in GeniE. Loads to mass. It is now much easier to convert point and line loads to mass for dynamic analysis. The conversion is automatic based on a user selection of load cases. The analysis model (FE model) will contain FE point masses instead of FE point and line loads. The benefit is that the concept model is kept intact. Previously it was necessary to use a script to convert the loads on the concept model or manually convert loads to point masses. In other words, it was necessary to maintain two almost identical concept models for static and dynamic analysis. Now one model is sufficient. Wind load calculation per the Projected Pressure Method. Previously this method was only available for wind surface loads. The new method is now the default option and applies to both members and surfaces. It is possible to select the Velocity Component Method. In addition, the ABS wind spectrum has been added to the list of available wind spectra. The new features provide greater flexibility in wind load computations for use in structural analysis. Improved handling of marine growth in time domain wave load analysis (also known as deterministic wave load analysis). The new program versions will automatically detect the intersection between a member and the instantaneous water surface and use this as calculation point for marine growth. Of significant importance is the weight (mass) of the marine growth in dynamic analysis. In addition, it will impact the buoyancy and wave load. Previously it was RELEASE DOCUMENT The Sesam May 2017 Release Page 5

8 necessary for the user to divide a beam at the water surface, meaning that it was necessary to have multiple models (one for each water depth). This is no longer necessary, as one model is enough to properly capture the effect of marine growth per time step and per wave load condition (water depth, direction, wave-height and phase angle). Print out of transfer functions for frequency domain wave load analysis. The new version of Wajac reports necessary information that can be cut and pasted into Excel for easy plotting of transfer functions from wave load analysis. Previously, it was necessary to use several Sesam programs to do this. The new feature thus simplifies the process of generating such figures. The graphs above have been made in Excel by cut/paste of Wajac generated data. They show that the shapes of the transfer function are identical for 20 and 70 wave periods. Hence in this example, dynamic analysis can be carried out with 20 wave periods to save analysis time. Further improvements in reporting. The user can decide to use one or two pictures per page as well as select which structural set and load cases to include. This will reduce the size of the report and it will be easier for the user to find needed information.. Faster dynamics and improved fatigue analysis of jacket structure. The new method for direct time integration leads to much faster dynamic analysis (in most cases the analysis will be more than 30 times faster than before) and allows for much larger analysis (model size and wave directions). Another benefit is that there is no longer a need to manually decide which eigenmodes to include in the dynamic analysis as this is irrelevant for the direct time integration method. The analysis will report the baseline shear RAO from dynamic analysis for comparison with the baseline shear RAO from the wave load analysis. Finally, the steady state (for each wave heading) is automatically detected and used in fatigue analysis this can also be easily verified by opening the vtf data generated during analysis and viewing the 2D graphs of the time histories in e.g. Excel. The example above shows the 2D plot of a time history from a dynamic analysis. In this case the analysis was automatically stopped (because of using such feature) when steady state has been reached. This analysis took 11 hours to run in previous Sestra versions (and other commercially available tools) but with the new release of Sestra it takes 20 minutes only. RELEASE DOCUMENT The Sesam May 2017 Release Page 6

9 Facilitate running dynamic spectral fatigue analysis. The latest version of the Sesam Manager will help engineers to run dynamic spectral fatigue analysis. It includes a template for running such analysis method called Spectral Fatigue. It will help to create the RAO graphs for dynamic frequency domain analysis results (base shear) to help find important waves to be used in the dynamic spectral fatigue analysis for direct time integration. Furthermore, the template will set up how to run the dynamic analysis (including compute wave loads by stepping through waves one cycle per wave direction is enough); run dynamic direct time integration repeating wave cycle until steady state detected; and create a result file with one cycle for each wave load after steady state has been reached). The pictures above show how to select the template for spectral fatigue and a typical RAO for base line shear. In this case the RAO from wave load (static) is compared with the RAO from dynamic structural analysis Automatically accumulate the fatigue damage. The fatigue analyses for various conditions are normally performed separately, but the damages at each hotspot need to be accumulated to give a full overview of the fatigue life. The analysis models are different in the various fatigue analyses meaning that time consuming hand calculations were used to accumulate the fatigue damage. This is no longer necessary as the damage for each hotspot can now be accumulated automatically. We believe that Sesam is unique in being able to do this. Accumulation can combine results from analyses based on using any of the 4 different methods available in Sesam i.e. use fatigue results from any of direct deterministic fatigue (or simplified fatigue), deterministic fatigue based in long term wave distribution, stochastic fatigue, or spectral fatigue. RELEASE DOCUMENT The Sesam May 2017 Release Page 7

10 Direct deterministic fatigue. Direct deterministic fatigue is a simplified method to assess the fatigue damage of the structure subject to determined cyclic loads. The user selects load cases to determine the stress range for use in deterministic fatigue analysis. This means that the procedure is the same as for deterministic fatigue except the basis for computing the stress ranges. The pictures below show the user interface of Framework and how to select various methods for computing the stress ranges. Import RAO for topside analysis. The utility tool RAOInputTool.exe that you will find under the GeniE installation location of your PC will help you to import and verify RAO s from other sources. It will create stochastic load cases for you (consisting of real and imaginary parts). You may use these to do member code checking based on frequency domain results (see below). It is easy to import RAO data and add relevant information for motion reference point, characteristic wave lengths etc. The picture to the right shows imported RAOs for verification purposes RELEASE DOCUMENT The Sesam May 2017 Release Page 8

11 Member code checking based on frequency domain results. Previously it was necessary to do such code checking in Framework including definition of code check properties and reporting in Framework. This is no longer necessary as all can be done from the GeniE user interface based on the same code check analysis and reporting for deterministic load cases. Frequency domain results can be imported from a hydrodynamic analysis like for example from a deck on barge transportation analysis or the analysis of a topside/module structure of a semi-submersible. Other examples can be when importing RAOs (see above). It is necessary to create a load combination for a complex load case (complex means that is has a real and imaginary part). When making the load combination the user needs to specify SCAN or a specific phase angle. The load combination may also include contribution from other deterministic load cases. When SCAN has been used, the load combination will automatically create results for every 10-degree phase angle for use in member code checking. Alternatively, if a specific phase angle is given the load combination becomes deterministic and can be used for member code checking, tubular joint code checking, plate code checking and other results processing. In this example a load combination Comb2_cmplx (made up of LC1_Static, LC_2Static and RC1_cmplx) will be scanned for each 10 degrees. The load case RC1_cmplx has been created from a SIN results file import. The process of using complex results is thus to a) make model in GeniE, b) Perform a wave load analysis or import RAO c) Structural analysis, d) import results back into GeniE, e) Create loadcombinations (i.e. auto scan or manual definition of phase angle) and f) perform a member code check using the load combinations. The picture above shows two ways of defining a load combination with Scan case or with user defined phase shift. The tabular report shows result from member code check. It will specify which phase angle yields the worst code check. RELEASE DOCUMENT The Sesam May 2017 Release Page 9

12 Much easier colour coding & labelling. Colour coding and labelling are now available from the pulldown menu. This means that you no longer need to select a relevant property, right click and select colour coding of labelling. Examples of use are shown below.

13 2.3 Sesam Floating Structure Package The package includes all Sesam programs needed to do make structural and panel models; perform hydrostatic, hydrodynamic and structural analysis; post-processing of results, code checking and fatigue. It includes GeniE (and supporting programs Sestra, Cutres, Stofat, Platework and Submod) and HydroD (and supporting programs Wadam, Wasim and Postresp). Compared to the December 2015 release the following has been updated for GeniE and HydroD related programs: The most important new features in the structural analysis tools are: Graphical display and labelling of finite element loads. Following a structural analysis, it is now possible to label finite element loads. The benefit is that this can be done graphically instead of looking up the details in a listing file. This is much quicker and easier when sharing results with others, as in the case of 3 rd party quality control. Mesh refinement by automatic dividing of the concept model. The mesh property Detail Box can be used to divide all structural parts at the border of a user defined volume. To refine the mesh inside the volume the user needs to manually apply new mesh densities before re-mesh. This will take longer time and require more user interaction than automatically refining the mesh, but the benefit is that the initial mesh does not have to be regular. In the example above three different detailed boxes have been used to automatically divide the structure (green, yellow and pink). Different mesh properties have been applied to the new structure and a refined mesh has been made. This method is a robust and an easy way to go from coarse to refined mesh with no requirements to the initial mesh. Hull girder load adjustment (HGLA) inside GeniE. The new version of GeniE allows users to automatically compute adjustment loads to FE model to ensure a correct shear and moment distribution on the cargo hold model per DNV GL and CSR OT&BC Rules. It requires that there is relevant data from Nauticus Hull available. Previously it was needed to do this manually by running Nauticus Hull and GeniE in sequence with manual data transfer. Yield strength assessment to include face plates modelled as beams. The functionality for Yield Check of Beams is available only for the Coarse Mesh Yield check according to CSR BC&OT or DNV GL Rules. Previously it was not possible to include beams in such operations. RELEASE DOCUMENT The Sesam May 2017 Release Page 11

14 Transfer of data to fatigue calculations according to ship rules. From a fine mesh analysis, relevant data for a fatigue check per CSR BC&OT rules may be exported from GeniE to NH FEA template. The user benefit is less manual work and less risk for human errors. The figures above show that a detailed box has been used to refine the mesh and that relevant data shall be exported to Nauticus Hull for fatigue analysis according to DNV GL or CSR OT&BC Rules Improved (faster and easier) workflow on design iterations. Design iterations based on plate code checking are now as easy to do as for design iterations of fixed structures. Following the redesign where the data for the capacity model is changed one can now click the Run all button also for plate code check. This means that there is no need any longer to manually update the concept model and manually re-run all analysis and perform the code check over again. Improved (faster and easier) workflow on design iterations. The performance on code check has been improved. Execution of CSRH/DNVGL rules are now done in parallel with preparing the code check. The example below for a container ship ( dof, 32 load cases according to DNV GL Rules) is now 3 times faster than before Automatically assign mesh density on imported models. Mesh densities are now computed (based on the mesh of the imported model) and applied to the relevant structural parts. This will generate a quality mesh when re-meshing is done. Previously it was necessary to re-apply mesh densities after Import. This is now automatic. The picture below shows the structural concepts and the automatically assigned mesh densities. RELEASE DOCUMENT The Sesam May 2017 Release Page 12

15 Drift force Drift force Make efficient mesh templates on top of core mesh technology. Core meshing has been improved and one example of such is for the Detailed Box option the refined mesh will now have mesh densities as specified in the input. Another example is meshing around a hole where a quality mesh is created based on number of elements along the edge of the hole and number of element layers. See below for examples. For the hydrodynamics tools the most important improvements are: 0,7 0,6 0,5 0,4 0,3 0,2 0,1 0,0 Forward speed in Wadam. Wadam has been enhanced to include small forward speeds. Alternatively, this can be regarded as wave/current interaction. Speeds or currents up to 1-2 m/s may be handled. For higher speeds Wasim must be used. The figures below show the effect on the mean drift force on a semisubmersible. + means that wave and current are in the same direction, - that they are in opposite direction. The smaller speed shows very good agreement between Wadam and Wasim, while some differences start to creep in at the higher velocity (1 m/s). WADAM '+' WASIM '+' WADAM '-' WASIM '-' v = 0.6 m/s Period (s) 0,8 0,7 WADAM '+' 0,6 WASIM '+' 0,5 WADAM '-' 0,4 0,3 WASIM '-' 0,2 v = 1.0 m/s 0,1 0, Period (s) RELEASE DOCUMENT The Sesam May 2017 Release Page 13

16 Added resistance. Wasim can now compute the mean drift force. When there is a forward speed the mean drift force is more commonly called added resistance. The figure below shows results for a containership (S-175) compared with two sets of model tests. The Froude number is Damping surfaces. The resonance problem for narrow gaps or moonpools can now be handled in both Wadam and Wasim. Damping is provided by defining a mesh on the free surface in the gap. On this mesh a damping term can be included. Similar resonance problems may also appear in other restricted areas, e.g. on top of the pontoons of a semisubmersible at small drafts. Easy meshing of free surface. Free surface meshes are important in many different contexts when using Wadam. It is required when doing second-order analysis or forward speed, and it is needed for free surface damping or irregular frequency removal, or just as a free surface mesh for wave elevation computation (offbody points). The tool HydroMesh has been extended to handle all these cases. The tool is accessed from HydroD. Some examples are shown below. Upper right: Damping lids for moonpools and gap, upper right: Fixed lid for removal of irregular frequencies, lower left: Free surface model for second-order analysis, lower right: panel model and free surface model as shown in HydroD. RELEASE DOCUMENT The Sesam May 2017 Release Page 14

17 64-bit Wadam. Wadam is now a 64-bit program. This has made it possible to extend many of the limitations in the program. You can now have more panels on the hull, more elements on the free surface, more frequencies, more wave directions and more phase angles. A corresponding update of Postresp which can handle much larger datasets has also been released. ITTC roll damping model. This is an updated version of the previous Tanaka/Kato model and is recommended by ITTC. Multi-body analysis improvements. Wadam can now handle a combination of fixed and floating bodies. It is also possible to compute sectional loads on body 1. A new stability program, HydroD 5.0 has also been released. This is the first version of the new HydroD generation. HydroD 5.0 is covering stability analysis. Compared to HydroD 4.9 the stability analysis has been enhanced and improved. More efficient and robust computations. More efficient generation of loading conditions. Fully flexible reporting engine. Reports are made in Word-format with use of company templates. The content of the report can be fully defined by the user. Templates for plots, tables and reports. Watertight and weathertight integrity surfaces. RELEASE DOCUMENT The Sesam May 2017 Release Page 15

18 2.4 Sesam Marine Dynamics Packages These packages include all Sesam programs (DeepC, Sima, Riflex, Simo, Mimosa and Vivana) needed for engineering analysis of marine dynamic systems, including various types of slender structures, e.g. mooring lines, risers and umbilicals, and complex marine operations, e.g. lifting/lowering analysis, floatover operation, etc. They interact with GeniE and HydroD to make a conceptual model and to read hydrodynamic results. The main benefits of these releases are listed in the following. Advanced functions in DeepC to support detail drilling riser and tensioner modelling. A new drilling riser example has been added to DeepC installation and some new functions has been added to DeepC GUI. This enables our users better simulating the complex components of drilling risers, such as slip-joint and tensioners, etc. For example, the drilling riser has a slip-joint which allows the line to move axially but not laterally. It can be modelled with a single segment in the upper part of the riser. The cross section used has very low axial stiffness to allow axial motion of the nodes at each end but high bending stiffness to stop lateral motions. Tensioners are simulated with lines with nonlinear axial stiffness without bending and torsion as shown below. The nonlinear stiffness can be defined as shown in the right plot. The upper ends relate to the floater using fairleads and the lower part is connected to the top end of the lower riser to simulate the tensioner ring connection. A new cross sectional damping properties function is also introduced to better simulate the mechanical damping in the tensioner system. RELEASE DOCUMENT The Sesam May 2017 Release Page 16

19 Waypoint function in Sima allows the user to specify several points along a desired path and let the dynamic positioning (DP) system to automatically control the floaters following the path. This could be used, e.g. in a DP float-over operation. Quick result check Basic result plots are now stored directly in the result folders under Conditions. The user may also plot them directly from the result folder. Improved reporting functions with automatic screenshot, plot and table functions. The user can define a template for a report, which could include any figures, plots and tables in the Sima task. It can combine results from different analysis or post-processing tasks. Furthermore, screenshot with user defined viewpoints can be saved, which means updated screenshots could be included automatically every time when the model is updated. RELEASE DOCUMENT The Sesam May 2017 Release Page 17

20 User defined task. This is an advanced function that allows the users to define a simplified GUI on top of an existing complex analysis. For example, users can specify several selected variables and controllers, as well as results singles and put them in a new window as an independent tool. 2.5 Sesam Pipeline Package Main update of the package is Simbuck v2.0 with the new VAS functionality included as an additional sheet. The VAS sheet allows the user to perform a probabilistic buckling analysis based on a Monte Carlo framework. The pipeline configuration (straight sections, horizontal curve and locations of rock cover) and trigger locations (vertical triggers and user defined buckling loads) may be specified by the user. Pressure and temperature profiles may be specified by the user. The distributions for axial and lateral frictions may be specified by the user. The buckling loads and the pipe-soil interaction is treated probabilistically in the analysis. That is, the buckling loads and soil characteristics are generated element-wise. The VAS sheet gives probability distributions as output. For instance, the probability of having a certain number of buckles, probability of buckling locations, probability of having a certain end expansion. RELEASE DOCUMENT The Sesam May 2017 Release Page 18

21 2.6 Sesam OWT Foundation Packages The Sesam OWT foundation packages include the analysis tools for fixed OWT foundation analysis Fatigue Manager and floating OWT foundation analysis Sima. Main benefit from the latest Fatigue Manager is that, users now can generate a Superelement directly in the Cloud. This will improve greatly the efficiency during Cloud solution since the user can make all the specification on their local machine but run all calculations in the Cloud. In previous versions, though the calculation could be finished in the Cloud, a Superelement needed to be created locally and uploaded to the Cloud. The file transfer process occupies quite a lot of project time during the design loop. The interfaces with BHawC and Bladed have also been improved to be consistent w.r.t. Superelement directions and coordinate systems. Please also refer to Chapter 2.2 and 2.4 for the updates of the calculations used by Fatigue Manager and Sima.

RELEASE DOCUMENT The Sesam May 2017 Release Page 20

23 3.2 Upgrading Sesam Manager The Sesam Manager database is compatible with previous versions. It is also possible to import data from previous versions using js (script), xml or zip files. The js and xml files recreate the workflow while the zip file also contains input and result files of the programs included in the workflow. The license file is the same as before. 3.3 Upgrading the structural analysis tools Upgrading from Previous GeniE Versions With the most recent version of GeniE (version ) it is easy to upgrade: Simply open the GNX file from a previous GeniE version. For older versions than GeniE version you need to export the GNX file. For GeniE version you may choose to use GNX or GNI as database format. There are four alternatives for migrating data from a previous version of GeniE. For a full description of data transfer capabilities and limitations please consult Chapter 10 in Volume 3 of the GeniE User Manual. You can download the User Manual from the Customer Portal before installing the programs. - The first alternative is using the js journal file make sure that it runs safely (File -> Read Command File) in the previous GeniE version before importing it into the new version. The journal file is complete and may contain analysis runs, code checks and report generations. It will also contain changes and deletions of model data, in short everything you did in the course of your work. - The second alternative is using the condensed js file (the so-called clean js file). This file is more or less complete for jackets and topsides where there are no curved structures. The environment and analysis set-up is included but note that code check data is not part of the clean js file. From version 6.6 and onwards the clean js file includes curved guide curves, curved beams and curved support curves. - The third option is by use of the XML import and export feature. The XML file contains a neutral definition of the workspace it is complete except for code check details and reporting. If you are upgrading from GeniE 6.3 or later the xml file includes code checking of beams. The functionality is available from File -> Export -> XML Concept Model and File -> Import -> XML Concept Model. - The final option is by use of the new GNX import and export feature. This option can be used when migrating data from the version to later versions of GeniE or when transferring data to new workspaces using this version of GeniE. The GNX zip file contains XML and FEM files. If you have multiple analyses all FEM files will be part of the data storage. You can use your existing license file to run the new version of GeniE. Please note that there are features (code checking of beams (CCBM) or plates (CCPL), modelling of curved structure (CGEO), mesh editing (CGEO) and mesh refinement (REFM)) that require a license key in addition to the one for the basic program version. For the execution of plate code check according to DNV GL Rules you must install the Rule Service The GeniE license for code check of plated structure (CCPL) is required. For use of PULS Excel and PULS Advanced viewer for refined plate code checking installation of Nauticus Hull is required. This requires a separate installation and separate license keys. Other Applications than GeniE For the programs Wajac, Sestra, Splice, Installjac, Framework, Platework, Submod, Usfos, Cutres, Stofat, Presel and Xtract the update information is found on the Customer Portal. If you want to convert soil data from Sesam GeniE to Usfos you should install the utility tool soil.exe from RELEASE DOCUMENT The Sesam May 2017 Release Page 21

24 The respective license files are the same as before. None of these other programs are using database technologies rather they have input files in form of *.jnl or *.inp files. This means that previous input data can be used to regenerate the data. 3.4 Upgrading the hydrodynamic analysis tools Upgrading from Previous HydroD Version Before you upgrade make sure you have copies of HydroD journal files (js files) to be used when regenerating your models in the new HydroD version. Importing the data to a new version will be more efficient if you use the feature to export a so-called clean js file. HydroD can also import old Prewad input files in case you have not used HydroD before. The license file for HydroD is the same as before. HydroD 5.0 is not backward compatible to HydroD 4.9. Beware that 5.0 is only for stability analysis. For hydrodynamic analysis HydroD 4.9 must be used. Other Applications than HydroD For the programs Wadam, Wasim, Waveship and Postresp, the update information is found on the Customer Portal. The respective license files are the same as before. Wadam, Wasim and Waveship are not using database technologies. Previous input data can be used as is to regenerate the data. Postresp has a database. Postresp 6.6 will read a database created by Postresp 6.5. It will also read jnl-files created for Postresp Upgrading the marine dynamic analysis tools Upgrading from Previous DeepC Version Before you upgrade make sure you have relevant js files to be used when regenerating your models in the new DeepC version. You can export a condensed js file (the so-called clean js file) and import this into the new program version. These actions are available from File -> Save Clean JS and File -> Read Journal File. The data transfer is complete, but you need to re-run your analyses. The license file for DeepC is the same as before. Upgrading from Previous Sima Version Sima will automatically convert the database from previous version to the latest version. The license file for Sima is the same as before. Other Applications than DeepC and Sima For the programs Simo, Riflex, Mimosa and Vivana, the update information is found on the Customer Portal. The respective license files need to be updated. None of the four programs are using database technologies rather they have input files in form of *.jnl or *.inp files. This means that previous input data can be used to regenerate the data. Some of the tools are Excel based meaning that the previous data can be used in a new program version. RELEASE DOCUMENT The Sesam May 2017 Release Page 22
