| Abstract: | A parallel unstructured mesh generation method is studied. Lohner's advancing front domain-splitting algorithm is improved so that the subgrids and their boundaries are more favorable for grid generation. An optimization strategy of subdomain's boundary is presented to improve the smoothness of the boundaries and the quality of grids. The conditions for receiving new points and elements are developed in the course of grid generation in subdomains. And a new strategy which receives new elements and refuses new points during the interface grid generation is presented,which saves calculation time. |
