Ng_LoadMesh() tries to read the geometry from the mesh file. If it was read before by Mesh::Load(), the preloaded geometry is replaced by ng_geometry (which might be garbage) This is a mere workaround, not a clean solution (Mesh::Load() should handle everything, including MPI distribution of geometry)
Netgen mesh generator
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 6.x supports scripting via a Python interface. Netgen is open source based on the LGPL license. It is available for Unix/Linux, Windows, and OSX.
