The situation of multi-region problemmay often appear when boundary element method (BEM) is applied inpractical problems especially in VLSI-CAD. It is difficult to deal withthis problem if traditional methods are used. Particularly, when theproblem to be solved contains a lot of materials, the advantages ofusing BEM such as simplicity, convenience and rapidity will be weakeneddue to the complexity of solving complex boundary element equation. Inthis paper a distributed algorithm for multi-region problem in BEM ispresented. This algorithm has been implemented in a distributed systemconsisting of 3 workstations to extract VLSI layout parameters. Theresults show that the calculation time of this distributed algorithm isless than that of the traditional methods. The results also demonstrate that this algorithm can speed up the computation and has the features of parallelism and high efficiency.
