Adaptive mesh refinement

Adaptive local mesh refinement for a reentrant corner using standard P1 finite elements on an Alberta grid.

Stokes-Darcy coupling

Coupled Stokes and Darcy flow in a heterogeneous medium. Taylor-Hood elements for Stokes and discontinuous Galerkin (degree 3) for Darcy have been used and solved in a fully-coupled approach.

Linear Acoustics

Linear acoustics simulation with discontinuous Galerkin methods. The domain consists of two regions with different speed of sound and reflecting boundary conditions are used.

Two-phase flow in porous media

Infiltration of a dense non-aqueous phase liquid into a heterogeneous porous medium. Solved with cell-centered finite volumes and pressure-pressure formulation.

Injection well in a saturated groundwater body with heterogeneous conductivity

The domain extensions of the groundwater body are 100m x 100m x 20m. The well is open only at the notches located at a depth of 4m - 8m below the upper domain surface. Solved with 1d/3d coupling of the continuous Galerkin finite element scheme on a parallel computer at a resolution of 200x200x200 grid cells on 40 processors. This plot shows two of the 40 processor blocks.
