NETGEN is an automatic 3d tetrahedral mesh generator. It accepts input from constructive solid geometry (CSG) or boundary representation (BRep) from STEP or STL file format. NETGEN contains modules for mesh optimization and hierarchical mesh refinement. NETGEN is available for free for non-commercial applications. It is available for Unix/Linux and Windows 98/NT.

NETGEN was developed mainly by  Joachim Schöberl within the  Special Research Project "Numerical and Symbolic Scientific Computing" at  the  University Linz.. It has been supported by the Austrian Science Fund  FWF.
