*SPSH
i1, i2
i1: Homogenized STL shell split toggle, 0 or other positive integer
i2: Log verbosity control, 0, 1, or 2
Use this card to split multi-entity homogenized STLs into shells during meshing so that each isolated support or lattice structure is segmented into a single entity before homogenization. Shells with less than 4 vertices are ignored. Triangles are considered part of the same shell only if they share edges. This improves meshing of homogenized parts as regions between shells will not be artificially filled in during meshing.
Use any i1 value other than 0 to turn this feature on. A value for i1=0 turns the feature off. Users can control the verbosity of the shell splitting feature by adjusting i2.
0 logs a minimal amount of summary information, like the total number of tets.
1 logs the wall time and number of tets for each of possibly hundreds of shells.
2 will also write a file resultsn STLName shell XXXX.stl for each individual shell.
Best Practices: This feature is not compatible with support structures created with raster or contour fragments.
