The Stefan Problem With Surface Tension
A Mixed Formulation Of The Stefan Problem With Surface Tension
Interfaces and Free Boundaries, vol 17, no 4, pg 427-464, Dec 2015.
Here are movies showing the evolution of a solid phase ``freezing'' into a liquid phase. The first two movies have iso-tropic surface tension. The others use anisotropic surface tension.
- Initial four pointed shape (isotropic surface tension).
- Initial five pointed star (isotropic surface tension).
