UDF Macro for enthalpy update scheme
 

Hello, dear all,

I am trying to write the UDF code to update the enthalpy, for the hot liquid solidification because of the cooling. But I could not find the appropriate Macro in the FLUENT document. The equation is something like:

(H)n+1 (n+1 means the next time step) = (H)n (n means the previous time step) + constant

Does any body have any experieince or idea about it?

Thanks in advance and have a nice day!
