ashish_kumar388 is on a distinguished road
I am solving a natural convection problem in a square cavity with solid-liquid phase change and gravity in negative Y- direction. I have written a UDF for density as function of temperature.
I have specified operating temperature to phase change temperature.
Do I need to specify operating density also.
Density in my problem varies from 905 to 928. I tried with giving specific density equal to 900 kg/m^3.
But the solution is not converging.

However, when I disable the operating density I'm getting convergence. Should I go ahead without specifying operating density.

Kindly Help.
