Abstract
In order to address the problem of grid-based method that a big change in the surface of the model will cause inadaptability of the algorithm, an algorithm of automatic hexahedral mesh generation based on logical grid is proposed. The proposed algorithm improves grid-based method and avoids generating initial grid in one time, but disperses the model into a series of section. Initial grid is formed by using vector intersection method for adjacent section. By modifying initial grid, a layer of mesh is formed. Every layer of mesh is assembled to form total meshes. By using improved grid method, automatic mesh generation for blocks of arch dam abutment with complex topography is accomplished. The results show that the algorithm proposed can adapt complex topography better. The elements are degradation automatically when the surface of model has a big change.关键词
