tascflow simulation
 

I am planning to simulate impeller volute together in Tascflow. Frozen rotor interface applied between impeller outlet and volute inlet. But there should not be any solid surface at interface. In my model vane thickness is coming at the interface. How to deal with it.

Can I simulate impeller and volute separately. In this case impeller can be solved by simulating one passage between the vanes. And after impleller solution how to put it around volute inlet.

Send suggestions....
