Guidelines for Retained Meshes
If you configured your session to use retained 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
Added surface and volume regions
Added any loads and boundary conditions that reference datum points
Added any idealizations that could affect the mesh
For shell-meshed features:
created the appropriate shell model by defining all surface pairs
defined idealizations to represent bars, weld elements, and contacts
Suppressed all geometry features modeled as bar elements—for example, a bar element that serves as a strut
Established connections between any load-transmitting surfaces or edges that do not touch or overlap
For hierarchical meshing:
created all hard points required to properly connect pre-meshed assembly components
established connections between all load-transmitting surfaces or edges on pre-meshed components, whether or not the surfaces or edges touch
applied mesh controls to resolve any node and element numbering conflicts
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
See Troubleshooting FEM Mesh Generation for help with mesh-generation problems.
