split

       'split' <set1> <set2>

This keyword is used to split lines, surfaces and elements.

The split command will not generate new surfaces but it will create points along the intersection between the surfaces in set1 and the surfaces (or shapes or faces) in set2.

So far only tetraeder elements (in set1) can be splitted by surfaces, faces or shapes (in set2). In this case 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.
