Longitudinal cut through the centre of the medium-density mesh. The mesh does not conform to the cut plane, making some elements look skewed.

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 smooth in most of the domain. Using a higher-order numerical method is more efficient than increasing the number of low-order computational cells in areas where the solutio...

... same mesh input has been used with three different mesh densities, resulting in a coarse mesh with a total of 18 676 tetrahedra, a medium-density mesh with 40 450 tetrahedra and a fine mesh with 123 628 tetrahedra. A cross-sectional view of the medium-density mesh can be seen in figure 4. The time step is adaptively controlled based on the maximum cell-based (28) and facet-based (29) Courant numbers. ...
