Currently we are developing two software packages, NETGEN, an automatic mesh generator and NGSolve, a finite element solver package, which can be used either stand-anlone or as a NETGEN add-on.
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.

NGSolve is a general purpose 3D finite element solver. Version 1.x supports scalar (heat flow), elasticity and magnetic field problems. The package provides C++ source code such that more advanced problem solvers can be built around it. NGSolve performs adaptive mesh refinement, the matrix equations are solved by optimal order multigrid methods.
