19 General improvements CAD import was updated to CADfix version The following file formats are supported: IGES (*.igs *.ige *.iges) STL (*.stl *.sta *.stb) Step (*.stp *.step) Creo up to version 3.0 (*.prt* *.asm* *.g *.xpr *.xas *.neu) CATIA V5 (*.CATPart *.CATProduct) CATIA V4 (*.model *.exp *.dlv *.dlv3 *.session) NX 9 Unigraphics (*.prt) SolidWorks up to version 2014 (*.sldprt *.sldasm) Inventor up to version 2015 (*.ipt *.iam) VDAFS (*.vda) ACIS (*.sat *.sab) Parasolid up to version 27(*.x_t *.xmt_txt *.x_b)

20 General improvements Optional auto-backup of projects while saving: No results Network drives supported

21 General improvements Translations and rotations of a component can be reset: No need to remove the geometry first Confirmation needed

22 General improvements Particles (single points) can be imported from CSV files:

23 General improvements Remote A default remote profile can be preset: The availability of cores is checked on the remote server during the start of the simulation.

24 General improvements Rigid dies with heat conduction can be used as trimming dies: Trimming (before/only) Trimming while forming

25 General improvements The progress display was improved: Individual process Multiblow (hammer and screw presses) Stage control Incorrect status information, e.g. if terminated on press force, was corrected

26 General improvements Improved calculation of automatic heat transfer coefficient: Now material properties of both contacting partners are considered.

27 General improvements Material database: The material group tool steel is limited to materials for deformable dies (elastic). Materials suited for metal forming simulations were moved to General steel New materials for sheet metal forming at room temperature: BH210 BH280 BH300 BH340 DDQ DP500 DP600 DP800 DQSK HCT600XD HCT780C HS440WGA HSLA350 HSS590 IF MS1400 TRIP590 TRIP600 TRIP780

28 General improvements Material data can be assigned to dies with type rigid die without heat conduction : If assigned, the assigned material properties are used If nothing is assigned, material properties from tool steel H-13 are used (similar to rigid dies with heat conduction )

29 General improvements Result value contact status: Contact to symmetries added Uniform for FE and FV solvers Result tree restructured:

30 General improvements New result value error element: Indicates inside-out elements Use element filter to show only the inside-out elements and their direct neighbors Belongs to standard result group

31 General improvements Usability of comparison view in THS plots was improved: Imported data can be activated & deactivated from selection.

32 General improvements For simulations using a counter blow hammer and the FV solver all energies (gross/net available/delivered) are always shown for the entire press. It is not anymore necessary to summarize the individual tool energies.

33 Sub-stages Backstroke: May now be larger than 100%, input may be given as distance, e.g. in mm Can be used in combination with terminate on tool forces Can be used if die positioned at BDC and automatic positioning of tool used

34 Meshing Improved self-contact: Hexmesh C folds ok V folds instable as sharp folds will create geometries impossible to be hex-meshed particularly if sharp edges are detected Tetmesh will be improved further in upcoming versions Example of large fold meshed with Hexmesh

35 Meshing Remeshing can be controlled: Based on criteria (default) Only forced Never (simulation will stop debugging) Symmetry Adaptive mesh refinement, type contact Symmetries do not cause refinement anymore. Tools will be selectable by user [development ongoing].

36 Hot forging (FV solver) Multiple (segmented) dies can be used also for screw and hammer presses. Time-ramp-up is supported also for screw presses. Effectively reduces the force peak at initial tool contact.

37 Hot forging (FV solver) New termination criterion on tool forces added: Stops the simulation when given tool force is exceeded Should be used together with solver step control time ramp up

38 Mechanical joining New process types self-piercing riveting, punch riveting, blind riveting and tensile test Optimized initial and advanced settings Automatic measuring (self-piercing riveting and clinching)

39 Mechanical joining New additional termination criteria: Self-piercing riveting Clinching

40 Mechanical joining If the sub-stage release workpiece from stationary dies is used, all sheets and adhesive layers are excluded from the release as a default setting.

41 Mechanical joining Modified strategy if inside-out elements occur (may occur if glue is used and/or mesh separation is required): Solver cutbacks first Forced remeshing Elements will be deactivated (if activated in the forming control) Stability improvement

42 Pressure welding New result value: Automatically calculated electrical contact coefficient New contact type for resistance spot welding: temperature drops from melting to solidus temperature contact glued Added support for segment-to-segment contact for application module pressure welding Electrical material properties (phase-dependent) can be imported from JMatPro

43 Optimization Any object attached to the process tree can be exchanged in a serial examination and optimization

44 Optimization Use create all optimization cases to create and start the simulation of (many) variants:

45 Optimization Serial examinations Can be carried out running several simulations simultaneously (if licenses available). A failed simulation will not stop the serial examination or optimization run anymore. For selected process types the components can be positioned automatically.

46 Not only for optimization Auto-positioning for initial positioning for selected processes: Friction spot welding Spot welding Self-piercing riveting Notes Positioning is done by translation along global z-axis. Lowest component is used as reference (position is not changed). Component roles for self-piercing riveting must be defined. Components without roles (e.g. fixings) cannot be positioned. Rivet is not positioned but punch is positioned on rivet's top.

47 Not only for optimization The initial meshing (in addition to remeshing) settings are kept if the geometry is exchanged.

48 Process chain simulations / interfaces Import results from casting simulation with Procast Geometry Temperature Shrinkage porosity Stress Export only one geometry and one step (increment) per *.unv file 3D geometries only

49 Process chain simulations / interfaces Import results from casting simulation with Procast Import UNV files with Geometry Mesh from file Unit of result values is read from UNV file and transferred to Simufact.forming automatically After importing the geometry, mesh + results are available in the object catalog Shrinkage porosity is converted into relative density

50 Process chain simulations / interfaces Export interface of simulated press forces to Brankamp process monitoring systems: Facilitate tool setup & increase die life Use simulated results as a reference for production Note: requires special license from Simufact and Brankamp

51 General improvements In case of a GUI crash memory dumps are written to allow easier debugging & customer support: MemoryDump files saved in folder %APPDATA%\simufact\MemoryDumps of the current user No customer data (geometries, material data, etc.) are stored Only activated if the setup was carried out with admin privileges

52 Top bugfixes Blocked read-only access by the solver to CUR, HIST and RES files was fixed. Incorrect stress transformation in dieload simulations with rotating dies fixed. Several reasons for occasional GUI crashes were resolved. Symmetry planes are now correctly transported to the next stage by the stage control if automatic workpiece symmetry is used. Not working output divisions based on stroke during backward stroke were fixed. Jumping forces in remeshing time steps have been fixed. Incorrectly shown validity in the license manager was corrected. In total almost 400 bugs were fixed.

53 Top bugfixes Resolved meshing issues SurfaceMesher: Various issues like occasional memory leak and very long meshing times or meshing failures have been resolved. HexMesher: An error was resolved that under rare conditions produced a mesh with holes on the surface. Sheetmesher: Incorrect mesh produced if geometry to be meshed had small holes or narrow notches was resolved.

54 Setup Supported operating systems: Windows 7 (64 bit), Windows 8 (64 bit) Linux (64 bit): FormingGP GUI and solvers only (mainly tested on RHEL 6.3 / CentOS 6.3) Graphic card requirements: OpenGL 2.1 or newer Min. 1GB RAM on graphics card Use newest driver available Note: If all colors are displayed grey when using the Windows remote desktop or a Teamviewer session, the graphics card drivers need to be updated on both computers.

55 Setup Simufact.forming GP (as well as Project and Quickpost) are installed with a separate setup using a separate path and their own solver.

56 Setup Settings have been made independent from installed version and can be transferred to new versions when the GUI is opened for the first time: The need to register with a password for the MPI service was removed:
