The principle of the virtual mesh that the hyper sphere determined by the computable nodes which cover the general nodes in n is further proved in this paper. The optimum design method for virtual mesh is established, the formulae for assessing the amount of computation is derived, and a practical approach to the problem of 'computation explosion' existed in mesh method for dealing with a large dimension for a long time is suggested. It shows that the virtual mesh method is particularly applicable to the optimum computation for complex structures, and it helps to find the overall optimal solution by remarkably reduced computation.
