The Linearized Membrane Stress is calculated as The Linearized Bending Stress is calculated as The Linearized Maximum Combined Membrane and Bending Stress is calculated as The Maximum von Mises Stress along the SCL is Page 8

9 Hide and Show Entities Why the tool was desired Users hoped FEMAP could have a similar tool to the Plot/Erase command in PATRAN API Features API script developed using API Programing Window Uses a number of different subroutines User-defined dialog box Uses Multi-Group Display Developed by Chip Fricke Page 9

10 Hide and Show Entities Using the API to Show entities (default behavior) Open model and run command. Select type of entity to Show, optionally toggle on the Include Related Entities option, then click OK. Use standard entity selection dialog box to select entities of chosen entity type, then click OK. Original Model Select Surfaces as the Entity Type and toggle on Include Related Entities Only the selected surfaces and related entities are now displayed Tip - If command is used again to Show, only the entities selected in that use of the command will be shown Page 10

11 Hide and Show Entities Using the API to Hide entities Select type of entity, toggle on Hide Selected Entities, and optionally toggle on the Include Related Entities option, then click OK. Use standard entity selection dialog box to select entities of chosen entity type, then click OK. Original Model Select Surfaces as the Entity Type and toggle on Include Related Entities Any entity not chosen to Hide will remain displayed Tip - If command is used again to Hide, the entities already hidden by the command will remain hidden and the newly selected entities will then also be hidden. Page 11

12 Hide and Show Entities Using the API to Reset View (Clear Hidden and Shown Entities) Select Reset View (Clear Hidden and Shown Entities) option, then click OK to restore the view to the original state before the command was used Page 12

13 Thicken By Data Surface Why the tool was desired If plate thickness needs to be varied in multiple directions, this was difficult or simply not possible to do with Modify, Update Other, Adjust Plate API Features API script developed using API Programing Window Allows use of any type of Data Surface, but Along Coordinates, Between Coordinates, Tabular Data Surface, or Arbitrary 3-D Data Surface are the types which should yield the best results Creates all of the needed property cards to attain variable thickness Developed by Dan Hinkle Page 13

14 Thicken By Data Surface Using the API Not required, but having all of the elements start off being a single plate property is recommended Run the script, select desired elements, choose a Data Surface that has already been defined, then answer Yes/No to OK to Minimize Properties (Slower) question 4 Point Bilinear Data Surface Locations and values shown in model Page 14

15 Thicken By Data Surface Model shown with Plate Thickness on and contoured using the View, Advanced Post, Contour Model Data command, with Plane Element Thickness selected Page 15

16 Calculate and Thicken Why the tool was desired If plate thickness needs to be varied to match surfaces of a solid, this was again difficult or not possible using Modify, Update Elements, Adjust Plate or even Thicken by Data Surface API API Features API script developed using API Programing Window Creates all of the needed property cards to attain variable thickness Any number of surfaces may be selected and the script will determine the appropriate thickness at each node using a ray-firing technique Stores thickness data on a temporary Data Surface Developed by Dan Hinkle Page 16

17 Calculate and Thicken Using the API Not required, but having all of the elements start off being a single plate property is recommended Position mesh in the middle (use Middler API, if needed) Run the script, select desired elements, choose upper and lower bounding surfaces, define a default minimum thickness values, then answer Yes/No to OK to Minimize Properties (Slower) question Solid Geometry of fictitious fin Shell mesh at middle of the fin Page 17

18 Calculate and Thicken 6 Bounding Surfaces selected on top 6 Bounding Surfaces selected on bottom Shell mesh of fin shown with updated thickness Page 18

19 Copy Functions Between Models Why the tool was desired Sometimes you may need to copy functions from one open model into other open models API Features API script developed using API Programing Window Using the API The Source model and all Destination models must be open Run the script, select any number of functions, then any number of Destination models. Developed by Patrick Kriengsiri Page 19

20 Embed Multiple Faces Why the tool was desired Geometry, Curve From Surface tools such as Pad and Washer are useful when trying to create a mapped mesh on surfaces embedding those surfaces may also be useful for creating a mapped hex mesh API Features API script developed using API Programing Window Using the API Surfaces should be subdivided before using this tool Run the script, then select only the surfaces to embed using the standard entity selection dialog box Developed by Andrew Jabola, Saratech Page 20

21 Embed Multiple Faces Original Geometry All One Part Surfaces selected for embed operation After command, multiple solids are now ready for sizing and hex meshing Page 21

22 Selective Display of Node IDs Why the tool was desired Users wanted to show all the nodes, but only have the IDs shown for selected nodes API Features Uses Text objects to create the temporary Node labels Could be modified to do the same for other entity types Developed by Andrew Jabola, Saratech Page 22

23 Selective Display of Node IDs Using the API Run the script to open the Select Node ID Manager dialog box Optionally, click Specify Color to select a color for the labels from the FEMAP Color Palette Click Select Nodes to use the standard entity selection dialog box to select the nodes When done with the temporary labels, use the command again and click Clear Node IDs Page 23

24 Create Multiple Load Sets from Multiple CSV files Why the tool was desired User had over 100 comma-separated value files created by MATLAB containing nodal IDs and load values, each of which needed to be imported into FEMAP to create an individual load set. API Features API script developed using API Programing Window Cycles through all files in a selected directory Load Set Titles match CSV file names Using the API Place all CSV files in a single directory Run script, then select any CSV file in directory to set directory path Developed by Dan Hinkle and Andy Haines Page 24

25 Create Multiple Load Sets from Multiple CSV files Values from Load Set 1 Values from Load Set 4 Page 25

26 AutoBoltMaker Why the tool was desired Using Custom Tools, Meshing, Hole-to-Hole Fastener for multiple holes can be quite time consuming. API Features API script developed using API Programing Window Using the API Surfaces need to be meshed before using this tool Run the script and answer question to enter a radius for the bolt or to select an existing beam property (used for every fastener created during each use of the command) Select any number of Curves using the Standard Entity Selection dialog box for Curves (will not use anything other than circular arcs) Developed by Andy Haines Page 26

27 AutoBoltMaker Select any number of curves In this area of the model Only curves which make up a pair of circular loops will be selected Rigid Spiders and a beam element using the selected property or entered radius will be created A variation of this command is also available which allows selection of a CBUSH Property with a reference coordinate system, then creates 2 rigid spiders and a coincident node CBUSH element equidistant from the independent node of each newly created RBE2 Page 27

28 Coincident Node CBUSH Coordinate System Display Why the tool was desired For coincident node CBUSH elements, a Reference Coordinate System must be set on the property. This script displays the coordinate system directions at each CBUSH location. API Features Code has checking to make sure only Spring/Damper Elements which reference a CBUSH property AND have a Ref CSys defined are used Appearance of arrows on triads (Line or Solid) is based on Color Mode for Coordinate Systems in View Options. Using the API to Show the triads Run the script and examine triads for each CBUSH Different colors used for triads representing rectangular and spherical Developed by Andy Haines Page 28

29 Coincident Node CBUSH Coordinate System Display Using different API to Remove the triads Use Custom Tools, Model Query, CBUSH CSys Display Reset command to remove the triads Rectangular CSys shown in X Direction = Red, Y Direction = Green, Z Direction = Blue Spherical CSys shown in Radial Direction = Yellow Theta Direction = Orange, Phi Direction = Cyan Page 29

30 Laminate Next Ply and Laminate Prev Ply - Improved Why the tool was desired Users want to be able to look at the same output vector on either the Next or Previous ply in a model without have to select it from the Select PostProcessing Data dialog box also works when looking at Global Plies API Features Simply adds or subtracts 200 to the current output vector, which signifies it is on the next or previous ply Similar to one shipped with FEMAP and can be found in Custom Tools, PostProcessing, but this one also does Global Plies Using the API Recommend creating icons on a toolbar to aid is use Click appropriate icon to go to next or previous ply Developed by Mark Sherman, altered by Andy Haines Page 30

31 Linear Combination using Base Output Set Why the tool was desired User had many output sets, wanted to be able to choose 1 set as the base set, then linearly combine the base set with any number of other selected output sets, one at a time API Features Creates multiple output sets ( Base set + 1 Other set) using the feoutputprocesslinearcombination call, one of several that now exist which make it easier to use the functionality of Model, Output, Process Using the API Model needs multiple output sets Run script, select Base set, then select any number of other output sets Developed by Andy Haines Page 31

32 Group from Freebody Why the tool was desired User wanted to create groups based on the elements of a Freebody or the nodes and elements of an Interface Load API Features Represents use of the Freebody Object Using the API Run script, select a Freebody or Interface Load and a group will be created automatically. Alternate version of this script, Groups from All Freebodies, creates a individual group for each Freebody entity in a model Developed by Andy Haines Page 32

33 Standard Analysis (Statics or Modes) Why the tool was desired Model is ready to be analyzed and you want to launch a Nastran job using a single command without seeing a single dialog box API Features API script developed using API Programing Window Shipped with FEMAP and can be accessed via Custom Tools toolbar Good example of how to use the API to create and modify the Analysis Set Manager Slight modifications can be made to run your standard analysis Using the API Model has everything needed for a standard static or modal analysis run Choose Custom Tools, Standard Analysis command Developed by Andy Haines Page 33
