IMPLEMENTATION OF THE BOUNDARY ELEMENT METHOD FOR THE 3D MAGNETOSTATICS ON DISTRIBUTED MEMORY ARCHITECTURE

Linear and homogeneous problems of the 3D Magnetostatics are of a Poisson or Laplace type. In this case, the Boundary Element Method is a technique which often offers, among others, important advantages over << domain >> types solutions, such as finite elements since it provides a great economy in computing time and memory amount. However, when the geometry is complex, a dense mesh is required, leading to a large linear system, of which the forming and solving times should be reduced. The Parallel Computing techniques offer new efficient tools in this respect. Our study is devoted to the presentation and the comparison of different parallel implementations of the Boundary Element Method for the 3D Poisson problems on multiprocessor computers with distributed memory. Experimental results are obtained on a Meiko Computing Surface with 32 T800 transputers.
