Solving Large Poroelastic Wave Models
Large poroelastic waves models and especially large multiphysics models, that involve poroelastic waves physics, can be solved using an iterative solver (see the application library example below). For iterative approaches, tight tolerances are recommended. The preconditioner can be either the multigrid (geometric multigrid or GMG) solving for both pressure and displacement (as in the example). An alternative is to use hybridization and a direct preconditioner for the pressure DOFs and another direct preconditioner for the displacement DOFs. Both should use PARDISO as the direct solver.
