A Parallel Multigrid Preconditioned Conjugate Gradient Algorithm for Groundwater Flow Simulations

The numerical simulation of groundwater flow through heterogeneous porous media is discussed. The focus is on the performance of a parallel multigrid preconditioner for accelerating convergence of conjugate gradients, which is used to compute the pressure head. The numerical investigation considers...
