A multigrid algorithm for cell centered finite difference approximations is examined. The cell centered discretization gives rise to a non-variational multigrid algorithm. It is shown that the \(W\)-cycle and variable \(V\)-cycle converge with a rate which is independent of the number of multilevel spaces. In contrast, the natural variational multigrid method converges much more slowly.
