SimLab Automation CAD Import SimLab’s Direct CAD Import gives access to design parameters exposed in CAD software and allows the definition of parameters inside SimLab that define feature modification (Regeneration), which enables the user to study the influence of design parameters on the result. The group information of entities like faces and edges can also be imported into SimLab as groups which enable the user to define mesh control, loads and boundary condition. Regenerating the model will retain the group information

23. Double click the dimension and enter the parameter name Assigning the Parameters (Contd.)

24. Copyright © 2012 Altair Engineering, Inc. Proprietary and Confidential. All rights reserved. Catia

25. CATIA knowledge ware allows to create parameters and assign it to features. SimLab gives access to these parameters and allows the definition of parameters inside SimLab to study there influence in results without redesigning the CAD model. CATIA – Knowledge ware

26. Step 1. Clicking the icon will display the dialog box. Step 2. To create a new parameter, click “New Parameter of type” after selecting its type(Length). The new parameter appears in the “Edit name” field. Define its name, value and click “Apply” Creating parameters in CATIA

27. Create the following two parameters BigEndRadius=26.0 SmallEndRadius=10.0

28. The new parameter will be listed in the specification tree. User can create any number of parameters with predefined value.

29. Tools | options | Infrastructure | Part infrastructure | Display tab provides options for customizing the display of elements in the specification tree. Checking “Parameters” and “Relations” will display those in specification tree Parameters and Relations in Specification tree

30. This is an example to show how the parameters is associated to a feature. In this example the radius of big end is associated to a parameter “BigEnd_Radius”. Step 1. Clicking the icon (from Knowledge tool bar) will display the dialog box. Step 2. Select sketch from specification tree and select the dimension for big end radius. The selected dimension will be highlighted in the formula dialog Using parameters

31. Using parameters (Contd.) Step 3. Select Add Formula

32. Step 4. Select parameter “BigEnd_Radius” from specification tree and click “OK” Using parameters (Contd.)

33. The new relation will be listed in the specification tree Using parameters (Contd.)

34. Step 1. Select “Generative Shape Design” Workbench Creating publication

35. Step 2. Select “Operations/Extract” Step 3. Extract the faces which are to be published Creating publication (Contd.)

36. The extracted face will be listed in the specification tree Creating publication (Contd.)

37. Step 4. Select Tools/Publication Creating publication (Contd.)

38. Step 5. Select the “Extract” feature from the tree Step 6. It can be renamed to user defined name by selecting the name field. This name will be the name of the group in SimLab Creating publication (Contd.)

39. To read the publication information from the CATIA file the application protocol is to be set as “214 iso” Select Tools | Options | General | Compatibility | STEP and set “Application Protocol(AP) to “214 iso” and click “OK”. This will enable the user to import the publications as “SimLab group”. CATIA – Publication

46. Copyright © 2012 Altair Engineering, Inc. Proprietary and Confidential. All rights reserved. Color spec Standard color coding should be followed. Colors can be applied in CAD systems or inside SimLab. Each feature should be identified with unique color. Import the model and use Render Mode | Face Color to see the colors assigned to faces. RGB values can be seen in output window when a face is selected. After applying meshcontrols to different features, export a mesh specification file using Color option. This spec can be imported to any model which was color coded with the same color standard. ( Ed: Holes – Blue, Planar Face- Red, Fillets – Green)
