%X A quadrilateral mesh generation scheme using recursive domain bi-divisions is enhanced in this paper.Robust mesh templates are designed,to provide a unified way for sub-domain meshing.The templates pose no restrictions on the numbers of boundary nodes(e.g.six or eight) of sub-domains,and can mesh the 'big' regular sub-domains bounded linearly in many cases,thus to highly improve the timing and storage performance of the algorithm.Coupling the new sub-domain mesh generation procedure with an automatic domain decomposition procedure,we obtain a new automatic unstructured quadrilateral mesh generation algorithm.Finally,mesh examples and simulation results are presented to demonstrate the capabilities of the new algorithm.
