Hi yan Thank u....

Rajeev Kumar Singh

Why in first place it has to be two separate UDF, in fact you should put all the macro in one C file and interpret it

Thanks sir. I have done it, I created two seperate UDFs for two different boundary conditions. Now I have put all in one

Andrea Boghi

You cannot "Interpret" two separate UDFs, but you can "compile" them.

I think it may be calculate as in article in attachment
