Abstract :
A new method for computing field quantities and forces is presented. By solving the differential equation analytically in a local post-process the finite element approximation achieves superconvergence. Compared to direct evaluation accuracy doubles. Numerical results are compared to analytic solutions in order to prove the rate of convergence. The method is efficient and easy computable
