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
Iterative splitting schemes for a soft material poromechanics model
This work addresses numerical solvers for a poromechanics model particularly adapted for soft materials, as it generally respects thermodynamics principles and energy balance, and develops two approaches that resemble the well known undrained and fixed-stress splits for the Biot model. Expand
Towards Hybrid Two-Phase Modelling Using Linear Domain Decomposition
Based on an Euler implicit discretisation, a linear iterative (-type) domain decomposition scheme is proposed, and proven to be convergent, that confirms the efficiency of the hybrid ansatz as compared to full two-phase model computations. Expand
