Debug of UDF in FLUENT

August 29, 2006, 16:37

Hello, everyone. Now I am using UDF in FLUENT. The file itself seems to be correct when it is compiled; however, the results are not satisfied. So I would like to process debug of the UDF to see what I get in one iteration for some varibles. Does anybody know how to do it? Or does anyone suggest some documents or references? Thanks in advance.

Why not embed 'Message' statements in your UDF. The 'messages' could write to the screen the results of calculations or simply extraction of flow data at each iteration.

I have found this helpful.
