Abstract:With the wide application of finite-element method to seismic exploration, some technical problems need to be solved urgently. A method for automatically forming the new finite-element grid is put forwards both the element information, expressed by grid point and the grid point information indicated with element are shown in the paper. The advantage is that two_ adjustable means can effectively control the number of finite elements and may be compatible with triangular elemenu and quadrilateral elements. Two examples of automatically forming the new finite-element grid for two models are given in the paper. This method proved feasible.
