| Abstract: | According to the demand of self-adaptive mcsh refining, self-adaptive refining algorithm of triangle element mesh is put forward. Meantime, in order to reduce calculation and data storing, dynamic aggregating algorithm of triangle element mesh is proposed. The criterion of spatial self-adaptive mesh refining and dynamic aggrcgation based on geometry is brought forward. The self-adaptive refining and dynamic aggrcgation of spatial triangle mesh is fulfillcd. |
