Hi,
I am working on a melting problem. By default FLUENT solves Energy eqn in terms of enthalpy so I have written a User Defined Scalar to solve for temperature. However, while doing so, the continuity residuals are beahving strangely.
Boundary Condition:
Left wall : 310K
Right Wall : 290 K
Top & Bottom : Adiabatic

On seeing the temperature contours, I am noticing something very strange and unrealistic. They max value is above 310 K!! This is an unrealistic solution and I am trying to figure out the cause.
Kindly give your suggestions.
Something has gone terribly wrong!!!

Regards,
Yash
