Getting a high-quality mesh can be the most time-consuming part of a finite element analysis, but the results make it well worth it. A good mesh is the balance of precision and computation time; quality meshes converge quickly, produce accurate results and do not produce errors.
For details on creating and controlling the mesh on your model, see the links below. For a quick overview of the steps in the meshing process go to The Meshing Process.
The majority of the meshing process involves the mesh settings. Click on the link below for the subject that you want more information about.
