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.

I installed Mecway which uses this product to create meshes. Unfortunately I needed to run the integrated topology explorer/doctor that mecway did not have so I loaded Netgen. It required me to install Opencascade which I did so I could import .stp files. I ran it on Windows and set it to include OCC but it still failed on loading .stp files. No documentation and no answers on the Web. Found one person with the same problem from a year ago and nobody helped him. Looks like the product might work very well for some but the lack of activity on the forums combined with bad documentation make the product all but useless.
Did not work anymore ! The TeTGen project is surely robust but Netgen CSG engine make it weak ! Just too bad !
