【Abstract】 Based on the space transformation concept and the Delaunay triangulation method, an approach for generation of anisotropic unstructured grids was proposed. The application of such grid to numerical solution of heat conduction problem with anisotopic thermal conductivity reveals that such anisotropic grid is efficient to anisotropic heat conduction problem.更多还原
