The classical solution of electromagnetic problems using the finite element (FE) method needs to assemble, store and solve an Ax = b matrix system. A new technique for solving FE cases, considered much simpler than traditional methods, shows that the assembling of the matrix A is unnecessary. The difference between these two techniques is the computation and processing time. The new one requires more...
This work describes the use of a solver with a modified LU preconditioner using an additional intersection parameter among the blocks in order to minimize the weakness due to the blocks decoupling. The LU preconditioning is tested on a cluster computer linked by a Gigabit switch. The program uses SPMD model and MPI library
