I wish to solve stefan problem ( melting of solid substance) along with convection in fluid domain. Initially I started with COMSOL Multiphysics and as an example you can refer to this simulation in this link.

The physics of the problem is as follows : A square cavity contains both solid (right domain) and liquid tin (left domain). The maximum possible temperature of the solid tin can be its melting temperature and hence the interface is fixed at this temperature. There exist a temperature difference between left and right boundaries such that solid tin will start melting. This velocity/movement melting interface is captured by an energy balance equation. In COMSOL, with this, it is possible to estimate the movement of the mesh using the same equation.

But I wish to switch to OPENFOAM. Hence, I would like to know what is the best approach to model this problem using OPENFOAM?

Thank you for your time and patience.
