Dynamic meshing in Solidification/Melting problem
 

Hi,

I am doing simulation of melting of sphere in a box in which the interface has convective boundary condition i.e. when the shell grows over the sphere after some time the shell melt and the sphere itself melt, the moving solidification front (box-sphere interface) has convective boundary condition. I want to define this boundary condition by using dynamic mesh.

Please help me to solve this problem
