A posteriori error estimates for mixed-dimensional Darcy flow using non-matching grids
Jhabriel Varela, Christian E. Schaerer, Eirik Keilegavlen +1
In this article, we extend the a posteriori error estimates for hierarchical mixed-dimensional elliptic equations developed in [Varela et al., J. Numer. Math., 48 (2023), pp. 247-2…
Persistent-variable thermal compositional simulation of multiphase flow with phase separation in porous media
Veljko Lipovac, Omar Duran, Eirik Keilegavlen +1
Thermal compositional multiphase flow in porous media with phase transitions involves complex nonlinear interactions among flow, transport, and phase equilibrium. This paper presen…
Data-driven linear solver selection and performance tuning for multiphysics simulations in porous media
