Abstract: Abstract An efficient finite element multigrid method on semi-structured triangular grids, based on box-relaxation, is proposed for the poroelasticity problem. A stabilized finite element scheme for these equations, based on the perturbation of the flow equation is considered. Numerical results confirm the good performance of Vanka smoothers for this saddle point type problem.
