Abstract
An implementation method of parallel finite element computation based on overlapping domain decomposition was presented to improve the parallel computing efficiency of finite element and lower the cost and difficulty of parallel programming. By secondary processing the nodal partition obtained by using Metis, the overlapping domain decomposition of finite element mesh was gotten. Through the redundancy computation of overlapping element, finite element governing equations could be parallel formed independently. And the uniform distributed block storage could be achieved conveniently. The interface to the DMSR data format was developed to meet the need of Aztec parallel solution. And the solver called the iterative solving subroutine of Aztec directly. This implementation method reduced the change of the existed serial program to a great extent. So the main frame of finite element computation was kept. Tests show that this method can achieve high parallel computing efficiency.
