| Popis: | A method for generating both equipotential lines and streamlines directly based upon nodal potentials and bilinear shape functions is presented. The method involves post-processing a finite element (FE) solution utilizing typical four-node isoparametric quadrilateral elements. The application of the method can be important in the interpretation of FE analysis results, especially when inhomogeneous, anisotropic, unconfined or/and other complicated conditions exist. Compared with conventional techniques to generate flow nets which depend upon both the potential and stream functions, the method presented is simpler and more powerful. |
