An efficient multiscale multigrid preconditioner for Darcy flow in high-contrast media
Changqing Ye, Shubin Fu, Eric T. Chung +1
In this paper, we develop a multigrid preconditioner to solve Darcy flow in highly heterogeneous porous media. The key component of the preconditioner is to construct a sequence of…
