Geometric Multigrid for Darcy and Brinkman models of flows in highly heterogeneous porous media: A numerical study

Guido Kanschat, Raytcho Lazarov, Youli Mao

We apply geometric multigrid methods for the finite element approximation of flow problems governed by Darcy and Brinkman systems used in modeling highly heterogeneous porous media…
