摘　　要：用分部优化的思想来处理有限元网格几何优化问题。将原问题转化成一系列设计变量很少的子问题 ,并提出一个多目标优化的算法进行求解。A decomposition optimization technique is used to deal with the geometrical optimization problem of a mesh in this paper. The original problem is transformed to a sequence of subproblems, in which the number of design variables is greatly reduced. An algorithm for multiobjective optimization is proposed to solve the subproblems sequentially. The efficiency of the algorithm is demonstrated by two examples.
