WebFor 2D, a maximum skewness less than 0.5 and an average of 0.1 are good. For 3D, a maximum less than 0.9 and an average of 0.4 are good. The lower the maximum skewness, the better the mesh. See Section 15.5: Mesh Quality for information on face and cell quality measures in TGrid. WebThe improvement is carried out by removing cells above the speci ed skewness threshold by collapsing cells, swapping faces, smoothing nodes, and inserting new nodes iteratively. Each operation is specialized, and the mesh will be modi ed only if the mesh is noticeably improved. The skewness before and after c ANSYS, Inc.
