Average temperature
 

hi,every one, i just began to study UDF and have a question want to get advices from u.
For u understanding easy, i would describe the question with simplification: There are two wall boundaries named Wall1 and Wall2 seperately, i want to calculate the average temperature of the two boundaries by using an UDF(i konw there may be other ways to get the value from the simulation results), could u please give me some advises? such as what macro should i adopt?
