Geometry Decomposition

Geometry decomposition is often required to generate an all-hexahedral mesh for three-dimensional solids, as fully automatic all-hex mesh generation of arbitrary solids is not yet possible in Trelis. While geometry booleans can be used for decomposition (and are the basis of the underlying implementation of advanced decomposition tools described here), Trelis has a webcut capability specially tuned for decomposition. It is also useful to split periodic surfaces to facilitate quad and hex meshing.
