A computerized mesh generation for finite element analysis program has been considered. The geometry to be analyzed is input and suitable subregions are defined interactivity. A natural coordinate mapping technique was utilized to obtain nodal points out of each subregion. The finite elements treated are two dimensional quadrilateral and three dimensional curved brick elements, which can be either linear or quadratic. Simple boundary conditions and loadings can also included.
The generated mesh can be displayed in perspective views, with element and nodal numbering. A bandwidth minimization program has been added. The developed program generates a neutral file that contains necessary informations for finite element analysis.
The program has been tested, generating input data in the format of SAPV and GTQSA, with three test probelms. Although its capability has been shown by these examples, future improvements are needed for more flexibility in the selection of element types and user convenience.
