Subscriber" rel="nofollow">tutorial in simulating a spiral turbine. The only thing that I changed is instead of inputting two outlets for the boundary conditions, I changed one to an inlet. However, the result that I got is very different from the one in the tutorial. As shown below, the fluid does not seem to pass through the rotating domain and it seems that it treats the contact region as walls instead of interfaces.March 25, 2022 at 11:16 amRob
Ansys EmployeeThe fact you have an interface and wall-13 & wall-14 suggests that some of the problems has been set up correctly. What I am wondering is why you only have one fluid zone. My guess is that you've labelled the stationary zone as rotating and the rotating zone is a solid.

Ansys EmployeeHow is the interface defined? Please post a screen shot of the interface panel & settings. Wall-13 & wall-14 shouldn't exist in the domain, they're there to catch situations where the interface isn't in contact.

SubscriberHello again I have performed a case check and it says "Review wall motion. Stationary wall motion relative to adjacent cell zone detected." Is this the reason why a wall seems to be forming in the contact regions?

Ansys EmployeeIf you set the centre zone to rotate you also need to set the rotor wall to rotate at zero relative velocity.
Please can you check the cell zones? If you have an interface you really ought to have two fluids.
