Numerical solution of second-order elliptic equations on plane domains. (English) Zbl 0717.65082
The paper presents a general discretization method for linear convective diffusion equations. The schemes are based on an integral formula and have the following properties:
1. They are particularly suited to the case when convection is dominant;
2. Solutions obtained by them satisfy a discrete conservation law;
3. A discrete maximum principle is valid.
The author shows that the finite element solution converges to the exact one with the rate O(h) in $$H^ 1(D)$$.
