Problem description: Poroelastic problem (structural problem)
The matrix ML_Geer has been obtained to find through a Meshless
Petrov-Galerkin discretization the deformed configuration of an
axial-symmetric porous medium subject to a pore-pressure drawdown.

method for axi-symmetric poroelastic simulations: numerical
study. International Journal for Numerical Methods in Engineering

preconditioner for unsymmetric indefinite matrices. Journal of
