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…
Enhanced Relaxed Physical Factorization preconditioner for coupled poromechanics
Matteo Frigo, Nicola Castelletto, Massimiliano Ferronato
The relaxed physical factorization (RPF) preconditioner is a recent algorithm allowing for the efficient and robust solution to the block linear systems arising from the three-fiel…
Efficient solvers for hybridized three-field mixed finite element coupled poromechanics
Matteo Frigo, Nicola Castelletto, Massimiliano Ferronato +1
We consider a mixed hybrid finite element formulation for coupled poromechanics. A stabilization strategy based on a macro-element approach is advanced to eliminate the spurious pr…
