| Abstract: | This paper presents a new parallel scheme on finite element analysis, in which an algebraic multigrid algorithm in conjunction with block iteration technique and multifrontal technique is developed to solve finite matrix equations. This method has advantages such as numbering of the finite element mesh in an arbitrary manner, simply programming organization, smaller core requirements and shorter computation time. The parallel program is developed on Dawning Tiangchao 1000A parallel computer. The PVM(Parallel Virtual Machine) system is used to handle communications among processors. Numerical examples are given to demonstrate the speedup and the efficiency of this method. |
