In this paper we study newly developed methods for linear elasticity on polyhedral meshes. Our emphasis is on applications of the methods to geological models. Models of subsurface, and in particular sedimentary rocks, naturally lead to general polyhedral meshes. Numerical methods which can directly handle such representation are highly desirable. Many of the numerical challenges in simulation of subsurface applications come from the lack of robustness and accuracy of numerical methods in the…

An Introduction to Multi-Point Flux (MPFA) and Stress (MPSA) Finite Volume Methods for Thermo-Poroelasticity

TLDR
This chapter gives a unified introduction to the MPFA- and MPSA-type finite volume methods for Darcy flow and poro-elasticity, applicable to general polyhedral grids, and refers to this discretization family as the MPxA methods.

Virtual element method for geomechanical simulations of reservoir models

In this paper, we study the use of virtual element method (VEM) for geomechanics. Our emphasis is on applications to reservoir simulations. The physical processes behind the formation of the

Finite volume methods for elasticity with weak symmetry

TLDR
The first set of comprehensive numerical tests for the MPSA methods in three dimensions are presented, covering Cartesian and simplex grids, with both heterogeneous and nearly incompressible media, and show that the new method is more robust and computationally cheaper than previous MPSAs.

Convergence of a Cell-Centered Finite Volume Discretization for Linear Elasticity

TLDR
The stability and convergence results presented herein provide the first rigorous justification of the applicability of cell-centered finite volume methods to problems in linear elasticity.

Stable Cell-Centered Finite Volume Discretization for Biot Equations

TLDR
Stability of the proposed discretization for the Biot equations is proved with respect to all relevant limits, and explicit local expressions for both momentum-balancing forces and mass-conservative fluid fluxes are available.

Open-source MATLAB implementation of consistent discretisations on complex grids

TLDR
An open-source Matlab® toolkit that can be used as an efficient test platform for (new) discretisation and solution methods in reservoir simulation is presented and examples of multiscale methods and adjoint methods for use in optimisation of rates and placement of wells are shown.

Cell-centered finite volume discretizations for deformable porous media

The development of cell‐centered finite volume discretizations for deformation is motivated by the desire for a compatible approach with the discretization of fluid flow in deformable porous media.
