| Abstract: | In this paper, the calculative region of finite elements is divided into several Sub-regions. in which the calcutative meshes, can be generated automatically. Th technic of the automatic generation of meshes, which used for the constant strain element (such as 3- node triangle and 4- node rectangle element) and linear strain elemerit (such as 6-node triangle and 8- node rectangle), is discussed. The sub-regions and net of the calculative region can be displayed dynamically by using the technic of computer graphics. The method used in this paper is clear in conception. simple in principles, and ore effi- cient. |
