Dear all,

I am new in CFD world. I want to write UDF for boundary conditions. My boundary conditions are as following:

at interface : Temperature fluid 1 = Temperature fluid 2
also for mass transfer : Relative humidity fluid 1= Relative Humidity fluid 2

I do not know, how can explain this relation by C program in UDF.

I appreciate if you kindly help me. please write or send me some examples.

Hi Samaneh,

Posts only need to be entered once, just so you know.

Why do you want to enter boundary conditions as UDFs? These are simple enough conditions that can be done within the menu system.

Good luck.
