Preparing the Geometry for Meshing Using Remove Details
To avoid unnecessary mesh refinements and bad quality elements relating to small details in the geometry, use Remove Details to prepare the geometry for meshing (see Figure 8-13). Small details, such as vertices with continuous tangent, short edges, small and narrow (sliver) faces, narrow face regions, and thin domains, can result in a high mesh resolution as each entity needs to be resolved by at least one mesh element. Small details can also influence the quality of the mesh elements, which might affect the possibility to reach a converged solution. See the section Mesh Element Quality for more information about element quality measures.

Remove Details automatically finds and removes small details from the finalized geometry. Modify the tolerance if the operation removes important details. After running the operation, resolve the mesh only in regions of importance for the accuracy of the solution.
See Removing Small Geometric Entities with Remove Details for a tutorial using Remove Details.
