CFX uses different turbulence models in different computational domains

Hi, everyone, i have a question about using different turbulence models in different computational domains, can anyone give some suggestions about how to setup it ?

I would strongly recommend against this if the domains are fluidically connected.

The only time I would consider this is if you had two fluid domains separated by a solid domain (so heat transfer is the link between the fluid domains). Try the "allow constant domain physics" expert parameter to see if you can do it - search the forum on details of how to apply this.
