| Abstract: | In this paper,a finite volume element method for 2D Sobolev equation is studied and a fully discrete finite volume element formulation and error estimates are derived.Some numerical examples illustrate the fact that the results of numerical computation are consistent with theoretical conclusions.Moreover,it is shown that the finite volume element method is more advantageous than others for finding numerical solutions of Sobolev equation. |
