摘要
We consider a multigrid algorithm for the cell centered difference scheme on triangular meshes using a new prolongation operator. The energy norm of this prolongation is shown to be less than 2. Thus the W-cycle is guaranteed to converge. Numerical experiments show that our operator is better than the trivial injection.
