Linear Robin-type Domain Decomposition scheme for Mixed Formulation of Richards' Equation
Åsmund v. B. Synnevåg, Wietse M. Boon, Florin A. Radu +1
In this work, we present a linear Robin-type domain decomposition scheme for solving the mixed formulation of Richards' equation (mLRDD-scheme), governing flow in variably saturate…
Multipoint stress mixed finite element methods for the linear Cosserat equations
Wietse M. Boon, Alessio Fumagalli, Jan M. Nordbotten +1
We propose mixed finite element methods for Cosserat materials that use suitable quadrature rules to eliminate the Cauchy and coupled stress variables locally. The reduced system c…
Solving Biot poroelasticity by coupling OPM Flow with the two-point stress approximation finite volume method
Wietse M. Boon, Sarah Gasda, Tor Harald Sandve +1
Finite volume methods are prevalent in reservoir simulation due to their mass conservation properties and their ability to handle complex grids. However, a simple and consistent fi…
H(curl)-based approximation of the Stokes problem with weakly enforced no-slip boundary conditions
Wietse M. Boon, Wouter Tonnon, Enrico Zampa
In this work, we show how to impose no-slip boundary conditions for an H(curl)-based formulation for incompressible Stokes flow, which is used in structure-preserving discretizatio…
Parameter-robust Preconditioners for the Stokes-Darcy Coupled Problem without Fractional Operators
Wietse M. Boon, Xiaozhe Hu, Xue Wang
We consider the Stokes-Darcy coupled problem, which models the interaction between free-flow and porous medium flow. By enforcing the normal flux continuity interface condition dir…
Neural network solvers for parametrized elasticity problems that conserve linear and angular momentum
Wietse M. Boon, Nicola R. Franco, Alessio Fumagalli
We consider a mixed formulation of parametrized elasticity problems in terms of stress, displacement, and rotation. The latter two variables act as Lagrange multipliers to enforce…
