Abstract
A key step of the finite element method for numerical computation is mesh generation. One is given a domain (such as a polyhedron; more realistic versions of the problem allow curved domain boundaries) and must partition it into simple "elements" meeting in well-defined ways. Locally fitting domain is a powerful idea leading to methods which trade the simplicity of mesh generation against difficulties with the boundary conditions. We develop an automated 3D mesh generator produces meshes:-locally fitted to the boundary. Major reductions in required storage for meshing have been obtained. The computational complexity of mesh generator is the O (n), where n denotes the number of mesh points. Therefore this technique is suited for generating rather fine grids, quite efficiently.
