Abstract

We introduce a new submesh strategy for the two-level finite element method. The numerical results show that the new submesh is able to better capture the boundary layer which is caused by the choice of bubble functions. The effect of an improved approximation of the residual free bubbles is studied for the advective-diffusive equation.
