Multigrid reduction preconditioning framework for coupled processes in porous and fractured media
Quan M. Bui, Francois P. Hamon, Nicola Castelletto +3
Many subsurface engineering applications involve tight-coupling between fluid flow, solid deformation, fracturing, and similar processes. To better understand the complex interplay…

Hybrid mimetic finite-difference and virtual element formulation for coupled poromechanics
Andrea Borio, François Hamon, Nicola Castelletto +2
We present a hybrid mimetic finite-difference and virtual element formulation for coupled single-phase poromechanics on unstructured meshes. The key advantage of the scheme is that…

Simulation of coupled multiphase flow and geomechanics in porous media with embedded discrete fractures
Matteo Cusini, Joshua A. White, Nicola Castelletto +1
In fractured natural formations, the equations governing fluid flow and geomechanics are strongly coupled. Hydrodynamical properties depend on the mechanical configuration, and the…
