How to deal with cad-geometry

A mesh based on hexader-elements has the better performance during the calculations but if the mesh should be derived from a cad-geometry it is often more convenient to create a tetraeder mesh as to modify or rebuild the geometry to make it meshable with hexader-elements. In this case the user can mesh the surfaces with unstructured triangles and export them in the stl-format (see ``send'') as a basis for an auto-mesher [4]. The following steps have to be done:
