| Abstract: | Transform of boundary fitted coordinates is implemented by finite analysis method. The 4-node super parameter's element constructed can replace the 4-node isoparametric finite element. Examples of computation on Laplace and Poisson equation show that the methods of this paper are simple and more accurate. |
