Accessing a zone
 

Hello all

Is it possible to access a particular zone in Fluent through udf's. I have to increase the velocity of particular domain with some value. Assume I am having four zones out of which I have to increase the velocity of first zone with some value. Is it possible through udf's

Regards Karthick

thread *tf; int id=3 ; tf=Lookup_Thread(d,id) where d is the domain pointer and Id is got fom the BC panel for different zone. once you get the pointer you could set the values. or in the define_profile you could check for where you are and set the values only when you are in the right zone . c_centroid could be used to get ur position. -Ajay

Hello ajay

I am having one more problem. If I try to patch the velocity with some values, turbulent viscosity is limited to 14285 cells error I am getting. Is it due to our udf...How can I get rid of it?

Hi Karthick,

If that is only warning message, you can pay no attention to it. Yo can set the limitation to the value you like.
