In 3D it is possible to remove small details in the geometry by running a geometry cleanup. Gaps, narrow domain regions, narrow face regions, sliver faces, small faces, and short edges that are smaller than the estimated, or manually set, detail size are considered to be small details and are therefore considered unwanted. This will typically reduce the number of elements in the mesh and therefore reduce computation time and memory consumption. If the geometry is a single vertex, cleanup is not available.
The default value is 0 or an estimated detail size. The detail size
<value> must be larger than
1e-6 times the size of the geometry and less then
0.1 times the size of the geometry. If
<value> is set to
0 when you run the analysis or automatic cleanup, it will be set to the estimated detail size.
