Package netgen-doc-4.4-12

NETGEN/NGSolve is a complete 3d finite element package. 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. 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. NETGEN/NGSolve was developed mainly by Joachim Schoeberl 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) and Robert Gaisbauer (OpenCascade interface).
