Block constrained pressure residual preconditioning for two-phase flow in porous media by mixed hybrid finite elements
Stefano Nardean, Massimiliano Ferronato, Ahmad Abushaikha
This work proposes an original preconditioner that couples the Constrained Pressure Residual (CPR) method with block preconditioning for the efficient solution of the linearized sy…

A novel block non-symmetric preconditioner for mixed-hybrid finite-element-based flow simulations
Stefano Nardean, Massimiliano Ferronato, Ahmad S. Abushaikha
In this work we propose a novel block preconditioner, labelled Explicit Decoupling Factor Approximation (EDFA), to accelerate the convergence of Krylov subspace solvers used to add…
