| Abstract: |
| All methodologies for the automatic mesh generation of quadrilateral elements are reviewed in this paper. A method for the automatic conversion of trianglar meshes to quadrilateral meshes is given. An algorithm for generation quadrilateral/trianglar meshes for arbitrary polygonal domains is presents. And geometric and topological propersities are discribed under this method. Further, the advanced data structure-links renovation criteria are discribed. Mech for sample ge-ometris are presented to illustrate the validity of the mesh generator. |
