    • An adaptive solution strategy for Richards' equation 

      Stokke, Jakob Seierstad; Mitra, Koondanibha; Storvik, Erlend; Both, Jakub Wiktor; Radu, Florin Adrian (Journal article; Peer reviewed, 2023)
      Flow in variably saturated porous media is typically modeled by the Richards equation, a nonlinear elliptic-parabolic equation which is notoriously challenging to solve numerically. In this paper, we propose a robust and ...

    • Efficient solvers for Richards' equation 

      Stokke, Jakob Seierstad (Master thesis, 2023-01-20)
      In this thesis we have sought to solve Richards’ equation. In time we applied a backward Euler discretization and in space we used a continuous Galerkin finite element discretization. The focal point was how to efficiently ...
