Abstract :
This paper describes a liner solver for finite element analyses on parallel computers. The present method of parallel computation is based on the overlapping domain decomposition. This lead to the improvement of convergence as well as reduction of the communication cost between processor elements. The numerical results show that this method has good convergence in the eddy current analysis
