UDF function for total energy
 

Hi everyone,

I am trying to write a UDF function that describes the relation between energy of outlet1 and inlet2 as shown in the picture below.

However, I do not know how can I transfer data between two boundaries, could someone help me to do that.

I thank you very much in advance.

There, it is shown how to "transfer" a quantity.

Thank you very much for your link
