Yes, the zone ID should be specified in the code for the component on which you would like to see the OSI contours in CFD post. (mostly, people use to see the OSI contours on the "wall", so the zone ID of the wall should be specified within the code).

My exact problem is how to enter the zone in the UDF?
That is, exactly what sentence(zone id of wall) should I enter into the UDF?

this is number which is written under ID, when you click "Cell Zone conditions" or "Boundary conditions" in Fluent GUI

In your UDF code line number 11 you need to edit at your convenience.

hello
i compiled udf of osi (see attachment) osi21.cand the fluent project was completed successfully!
but I don't know exactly in what time range the osi is calculated?!
First, I run three cycles and then I save the results of the fourth cycle.
thank you!
