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.
