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…
