A new adaptive finite element method for convection-dominated problems is presented. A special feature of the method is that it is based on a Petrov-Galerkin scheme for spatial approximation at a typical time-step which employs test functions chosen so that the approximate solution coincides with the exact solution at the nodes of finite element grid. This procedure makes possible the derivation of /rul,l' local a posteriori error estimates and a very elTcctive solver. Numerical examples are… CONTINUE READING
