We present a modular toolbox for parallel nite element simulations on distributed memory systems. The library named PadFEM includes a graphical editor for specifying domains with boundary conditions, automatic mesh generation, automatic mesh partitioning and mapping onto the processors of a MIMD-system. The parallel FEM-simulation uses the preconditioned conjugate gradient method. The parallelization is based on PVM which guarantees portable parallel code. The current implementation is able to solve the two-dimensional Poisson equation in arbitrary domains with mixed Dirichlet- and Neumann-type boundary conditions using triangular meshes. The modular structure based on the idea of programming frames allows an easy extension to other problems. 1, |
