Resum
The stability and accuracy of the forward Euler scheme for the semidiscrete problem arising from the space discretization of the convection-diffusion equation using the SUPG formulation are analysed. Both linear and quadratic finite elements are considered. The stability limits are derived for the one-dimensional problem and a heuristic criterion is proposed for the multidimensional equation. Some numerical experiments are conducted in order to assess the performance of different finite elements...
