Ocellaris: a discontinuous Galerkin finite element solver for two-phase flows with high density differences
Tormod Landet, Mikael Mortensen
In free-surface flows, such as breaking ocean waves, the momentum field will have a discontinuity at the interface between the two immiscible fluids, air and water, but still be sm…

On exactly incompressible DG FEM pressure splitting schemes for the Navier-Stokes equation
Tormod Landet, Mikael Mortensen
We compare three iterative pressure correction schemes for solving the Navier-Stokes equations with a focus on exactly divergence free solution with higher order discontinuous Gale…

Slope limiting the velocity field in a discontinuous Galerkin divergence free two-phase flow solver
Tormod Landet, Kent-Andre Mardal, Mikael Mortensen
Solving the Navier-Stokes equations when the density field contains a large sharp discontinuity---such as a water/air free surface---is numerically challenging. Convective instabil…
