UDF to iterate momentum source for desired flow

chtyler · June 19, 2013, 16:06

I'm pretty much a newbie with Fluent, so please forgive what may be a simple question. I have a model with a momentum source to set a recirculation rate. I'd like to write a UDF to adjust the momentum source in a transient simulation to get the desired recirculation rate. I cannot, however, find the appropriate macro to set the momentum source. Can someone point me in the right way?

Regards,

Chris

Try out DEFINE_SOURCE macro. An example is give in the UDF Manual
