%description
NETGEN is an automatic 3D tetrahedral mesh generator. It accepts
input from constructive solid geometry (CSG) or boundary
representation (BRep) from STL file format. The connection to a
geometry kernel allows the handling of IGES and STEP files. NETGEN
contains modules for mesh optimization and hierarchical mesh
refinement.
