UDF fluent, Cell Zone
 

Hi

I'm writting a UDF for diffusivity in my geometry, but I want to use the UDF for a specific cell zone in there. What command should be used before my UDF code?

Thanks a lot!

Hi,
each specific zone has its own thread ID which you can use for specification. So before using this UDF, separate your zone to achieve different thread ID in FLUENT.

Bests,
