WebJun 6, 2024 · Here are two tips on meshing thin bodies: 1 Check the defeaturing size. Reduce the defeaturing size below the thin dimensions to capture the thin features properly. 2. Check mesh size. If it is too coarse on the thin feature, use fine sizing. Featured Articles. WebAnsys Mechanical offers a wide array of tools to help you control your mesh density. There are global mesh controls that control the mesh size. This setting may be established for the entire model as well as local size controls, allowing refinement in areas of interest.
