PadFEM: A Portable Parallel FEM-Tool
نویسندگان
چکیده
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, automaticmesh 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 Dirichletand Neumann-type boundary conditions using triangular meshes. The modular structure based on the idea of programming frames allows an easy extension to other problems.

Comparative Analysis of High Performance Solvers for 3D Elliptic Problems
The presented comparative analysis concerns two iterative solvers for 3D linear boundary value problems of elliptic type. After applying the Finite Difference Method (FDM) or the Finite Element Method (FEM) discretization a system of linear algebraic equations has to be solved, where the stiffness matrix is large, sparse and symmetric positive definite. It is well known that the preconditioned ...

This paper introduces a new method for accelerating current sluggish FEM and improving memory demand in FEM problems with high node resolution or bulky structures. Like most of the numerical methods, FEM results to a matrix equation which normally has huge dimension. Breaking the main matrix equation into several smaller size matrices, the solving procedure can be accelerated. For implementing ...
