Create new FEM and Simulation files

  1. Open a part file and choose Home tab→Context group→New FEM and Simulation .Note: To modify the default file name suffixes appended to the part file name, choose FileUtilitiesCustomer Defaults. Then select SimulationPre/PostGeneralFE Model and Simulation Create.

  2. If you are in Teamcenter Integration mode using the Teamcenter for Simulation data model, type a number and evision for the FEM part, the Simulation part, and the idealized part. Alternatively, click Assign to automatically generate unique identifiers.

  3. (Optional) To create a FEM that is not associated with a master part (for example, if you plan to import FE data from another program), clear the Associate to Master Part check box and proceed to step 7.

  4. (Optional) To create a FEM that is associated directly to a master part (that is, if you are not performing any geometry idealization), clear the Create Idealized Part check box.FEM files are typically associated with an idealized part. The idealized part is an assembly instance of the master part. All geometry idealization is performed on the idealized part.

  5. If your part contains multiple solid or sheet bodies, from the Bodies to Use list, specify which bodies to include in the FEM and Simulation files:All Visible—Include all the currently visible solid or sheet bodies from the master part.Bodes that are not currently visible are not included.Note: The software does not remove a body from a FEM file if you later hide the body. If you later display additional bodies, the software automatically adds those to the FEM file.All—Include all solid or sheet bodies from the master part.Any new bodies that you create with idealized part commands (such as Midsurface or Partition) are automatically added to the FEM file.Note: Because lightweight facet bodies contain no polygon edge or face data, you cannot create a FEM on lightweight facet representations in assembly reference sets. If you select All, the software skips any lightweight facet bodies in the assembly part.Select—Include only the solid or sheet bodies that you select.When you select this option, Type Filter and Selection Scope become active in the Top Border bar, and you can select solid or sheet bodies in the graphics window. However, you cannot select facet bodies.Any new bodies that you create with idealized part commands are not automatically added to the FEM file. You must manually edit the FEM file to add any additional bodies.None—Creates FEM and Simulation files that include no bodies from the master part.Note: These options have no effect on the idealized part file. That file always contains all the bodies from the master part.

  6. (Optional) To include CAD reference geometry (such as points, curves, or coordinate systems), click Geometry Options and select the geometry to include.

  7. From the Solver list, select the solver that you want to use.

  8. From the Analysis Type list, select the type of analysis that you want to perform.

  9. (Optional) If the 2D Solid Option list appears and you want to include axisymmetric, plane strain, or plane stress elements, select the appropriate plane for the 2D solid elements, as well as the axis of rotation.

  10. (Optional) In the Description group, type a description of the model.

  11. Click OK.The software creates the idealized part (if applicable), the FEM polygon geometry representation, and the Simulation file, and prompts you to create a solution. You can create the solution now, or wait until later to create one or more solutions.The new simulation appears in the graphics window.The Simulation Navigator displays the new Simulation file, the FEM file, and the new solution (if you created one). It also includes containers for boundary conditions and entities such as coordinate systems or groups. mypart_sim1.sim mypart_fem1.fem CSYS Groups Fields Regions Simulation Object Container Constraint Container Load Container Solution 1 Simulation Objects Constraints Subcase – Static Loads 1 Loads
