| Abstract: | To find out the finite element solution for a class of nonlinear parabolic eqaution,a finite element method with moving grid is presented,in which a different grid is employed on the Spatial domain at different time. Furthermore the optimal error estimations between the exact solution and the FEM solution are obtained. |
