Problem with turbo initialization
 
Hello there,

I have a problem with Turbo Initialization in CFX Post. (Ansys 12.0.1)

I have a tube with two domains. One streamwise upside, one down. Each one has a hub, a shroud and some blades.
For the upper one, the hub goes all through, and the initialization is done easily. For the second domain, I get into trouble.
I chose hub, shroud, blades.
I chose Domain interface as Inlet, as I did on Domain 1 as outlet.
I chose the correct outlet.

But CFX won't get me into turbo mode. It says that either one region or the axis is not set correctly.

Someone told me, that this can occur if the hub ends before the shroud. This happens to me. But I don't know if this is the problem.

For your interest: I have a stream with a strong vortex and want the circumferential velocity on an hub to shroud chart. If there is any workaround, I will go with that.

Thanks in advance, and sorry for my spelling. English is not my mother tongue.
