Hi guys,
I'm trying to simulate an hydrokinetic turbine, so I split my domain with a rotating and static domain. My problem is the connection between theses two interfaces...I you take a look at the streamline, the vortex downstream the turbine just stop immediately at the end of my rotating domain and begins before the blades! I could use some help here.. In CFX-Pre, my interface setting for interface models are : option : general connection Frame change : Frozen rotor Thank you for your help!

Do you use the sliding mesh technique?

Is your simulation converged? Have you run it long enough to convect the flow to the outlet? This is exactly what happens if you have not run it long enough.
