split

   'split' [<set> <set>] |[<line> <point>]
This keyword is used to split lines, surfaces and elements stored in a first set by surfaces or shapes given in a second set. Also A single line can be splitted by a given point (see “pnt” how to generate a point on a line). Only surfaces without holes can be splitted so far.

So far only tetraeder elements (in set1) can be splitted by surfaces, faces or shapes (referenced by set2). The splitted tetraeder elements will be replaced by new tetraeder- and pentaeder elements. It can be used to cut out parts of the mesh to be either used directly in other models or which can be remeshed with tets based on an stl-file derived from them. Or it can be used to apply damages to a structure. See “How to map loads” in the appendix on how to map loads to the new created nodes from the original mesh.
