Reply To: How to give viscosity and surface tension under material properties for a solid melting problem?

Thanks a lot for your reply. I read about it and found that viscosity of solid is not that important as Fluent itself adds a Darcy's source term in the momentum equation to suppress the velocity in the solid phase.
As for the surface tension, I know that Fluent assumes the solid to be a fluid of high viscosity. My main doubt was about the Marangoni stress term which I was adding through a UDF. I realised that I should add it only after temperature of a cell has reached above the melting point.
