Hi everyone

I need some regarding a CFD simulation im doing.
Im currently using ANSYS CFX to similate a cooling fan on the volute.
The boundary conditions are as follows:
[*]Analysis type: Steady state[*]material: air ideal gas[*]heat transfer model: total energy[*]turbulence model: SST[*]35000rpm[*]inlet pressure@70C=0.9bar[*]refererence pressure=0[*]massflow outlet=1.3kg/s

The interface models are as such:
[*]inlet pipe and rotaiting domain: frozen rotor[*]volute and rotating domain: frozen rotor

Here is my problem.
The velocity contours from the rotating domain dont seem to merge will with the volute however im not sure how to solve this problem.

I have attached images to the thread. I would be grateful for any kind of help.

Thanks in advnace

The reason is discussed in this related FAQ: https://www.cfd-online.com/Wiki/Ansy...f_reference.3F
