In this paper, a method is described for automatically generating graded un- structured triangular meshes in polygonal domain or tetrahedral meshes in poly- hedral region. For a given set of assigned nodes with the corresponding spacing values, the method will generate a distribution of well-placed nodes on boundary and in the interior of the domain and then give a graded mesh.
The postprocessing for 3-D finite element methods is discussed in detail. For anarbitrary section in 3-D domain, the data processing of planar mesh is presented inorder to draw the contour map, the shaded map, the surface map easily and exactly.
