In this paper, we shall discuss a class of nite element discretization techniques based on two nite element spaces on one coarse and one ne grid. On the ne space, only symmetric positive deenite equations need to be solved for a nonsymmetric or indeenite linear equation and only one linear equation need to be solved for a nonlinear equation. It is shown… CONTINUE READING
