| 摘 要： | 根据多色染色理论，在同一节点有任意多个单元邻接的情况下，对有限元的单元进行了分类；在刚度矩阵组集时，同类单元可以并行计算，从而提高了组集效率．该并行算法在PVM(并行虚拟机器)并行平台上进行了具体实现，取得了较好的并行效率．

| Abstract: | Based on the theory of multi-color dyeing, theelements of FEM were sorted with arbitrary number of elements in the neighborhood of the same node. While composing the stiffness matrix, the same set of elements can be treated by parallel computation. So the efficiency of composing the stiffness matrix was raised. The parallel algorithm was carried out on parallel platform PVM with good results. |
