Assemblies concepts in Pre/Post

Pre/Post makes extensive use of Assemblies capabilities to define your CAE model. To take full advantage of the features available in Pre/Post, you are encouraged to become familiar with the basic features of assemblies as described in the Help.

Unlike standard CAD assemblies, which consist of piece part files and subassembly files, an assembly in Pre/Post consists of Simulation files (which define boundary conditions and solution options), FEM files (which define mesh geometry, nodes and elements, and physical properties), and part geometry files (which contain idealized CAD geometry or master model geometry).

This architecture provides several advantages when working with analysis data:

• You can easily reuse geometry and mesh data in multiple analyses. See CAE model files.

• You can use assembly loading options to control the use of system resources when working with large models. See Using Assembly Load Options for CAE model data.

• You can assemble component FEMs into an assembly FEM. See Assembly FEMs.

• You can set the work part and the displayed part independently. See FE model in context.
