Help in Phase-Change Problem
 

I was trying to start with the phase change problem using FLUENT 5.3.18 and I follow the setup procedure (Phase Change Setup). After activating the: Define-->Models-->Energy from the menu and typing the: define-->models-->melt-freez and typing y [yes] for the yes and no question and I received a message :

Error: CAR: invalid argument [1]: wrong type [not pair] Error Object: #f.

Does it means that the Fluent version in our department didn't support the phase-change problem? Because from the help menu file that I have read I should be able to solve phase change problem.

Thanks for consideration on my problem.

Hi, Just answer my self. The problem has been solved. You need to open the mesh first before changing the parameter of the melt-freez parameter (mesh.msh file). Thanks
