Contrib interTrackFoam
From OpenFOAMWiki
interTrackFoam is part of the development extended version of OpenFOAM and is not part of the standard release from OpenCFD. The interTrackFoam solver solves a partial differential equation to predict vertex motion in one or two-phase flow. The advantage of this approach over interface capturing methods is that the interface can remain sharp and numerical smearing is avoided.
