# Iterative solvers for Biot model under small and large deformations

@article{Revern2020IterativeSF, title={Iterative solvers for Biot model under small and large deformations}, author={Manuel Antonio Borregales Rever{\'o}n and Kundan Kumar and J. Nordbotten and F. Radu}, journal={Computational Geosciences}, year={2020}, volume={25}, pages={687 - 699} }

We consider L-scheme and Newton-based solvers for Biot model under large deformation. The mechanical deformation follows the Saint Venant-Kirchoff constitutive law. Furthermore, the fluid compressibility is assumed to be non-linear. A Lagrangian frame of reference is used to keep track of the deformation. We perform an implicit discretization in time (backward Euler) and propose two linearization schemes for solving the non-linear problems appearing within each time step: Newton’s method and L… Expand
