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. Netgen is open source based on the LGPL license. It is
available for Unix/Linux and Windows.

NETGEN was developed mainly by Joachim Schöberl within project grants from
the Austrian Science Fund FWF ( Special Research Project "Numerical and
Symbolic Scientific Computing", Start Project "hp-FEM) at the Johannes
Kepler University Linz. Significant contributions were made by Johannes
Gerstmayr (STL geometry) Robert Gaisbauer (OpenCascade interface).
