Guidelines for Transient Meshes
If you configured your session for transient meshing, make sure that you have completed the following tasks prior to meshing a part or an assembly:
• Simplified the part or assembly to remove features unnecessary for finite element analysis
• Suppressed any geometry whose only purpose is to serve as a vehicle for meshing a particular element type—for example, a solid used for placement of bar elements
• Assigned a material to the part or assembly
• Added all required loads and boundary conditions to the part or assembly
• Defined any idealizations
• For shell-meshed features:
◦ created the appropriate shell model by defining all surface pairs
◦ assigned material to shell pairs and solid portions of the model
◦ defined idealizations to represent bars, connections, weld elements, and contacts
• For assembly components that need to transmit loads, established
connections between surfaces or edges that do not overlap or touch
• Defined analyses
• Applied the appropriate
mesh controls to control the characteristics of the mesh
• Optionally set up any predefined criteria in the
configuration file against which to evaluate the quality of the mesh
