| Abstract: | In this paper the generation method for 4- node-quadrilateral element is deeply studied. Based on the work done by formers, and in order to solve the problems such as automatic zone-dividing ,intergral generation for the zone which has a complex boundary,artomatic generation for multiply connected domain,a new algorithm is given. The new algorithm improved the validity of the system. |
