Dear all,

I'm doing a simulation about the curtis stage of a steam turbine. Here is single passage setting in cfx-pre and it runs successfully.

Now I'm attempting to add an injection hole on the first rotor as casing injection simulation. There is a tip clearance on the first rotor, and small volume of steam flow is injected into the tip clearance through the injection hole.

My question is the interface setting between tip clearance and injection hole. The clearance domain is rotating while the hole domain is static, so I choose the "frozen rotor" interface,but an error occurs in the cfx solve manager:

It's the problem of the interface between tip clearance and injection hole. How could I deal with it in interface setting?
Thanks a lot!
