If You Use Transient Meshes
If you configure your session for transient meshing, be aware that:
Creo Simulate assumes that, even if you stored a mesh for the model in the past, you do not necessarily want to reuse that mesh in the current session. Therefore, the software does not automatically import any existing meshes when it brings your model into FEM mode. If you decide you want to use an existing mesh, you can manually retrieve it.
Creo Simulate only retains the mesh while you are in the Mesh menu or the Run FEM Analysis dialog box. If you leave this menu to perform modeling or analysis definition tasks before you run your analysis, the software deletes the mesh. In other words, for transient meshes, the software expects you to start a run immediately after creating a satisfactory mesh. Thus, you should define your model using the following sequence:
1. Create all modeling entities, idealizations, and properties.
2. Define all analyses.
3. Mesh the model.
4. Run the analysis.
For assembly models, you can only perform flat meshing. Because transient mesh sessions do not call existing meshes, you cannot create a hierarchy of existing meshes within the assembly model.
If you want to save a mesh in transient mesh sessions, you must use the File > Save FEM Mesh command.
If you decide to configure your session for transient meshes, be sure to observe the guidelines for working with transient meshes.
