Hello,
this is my first post here, I appreciate every help and try to be clear with what I was going for.

I'am trying to setup a turbine flutter simulation. The whole domain (see attachment) consists of an inlet (quite close to the vane row), vane row itself, blade row and an outlet part which extends quite long in axial direction. Using DesignModeler I was able to extract a mesh for the vane including the inlet part and a mesh for rotor and outlet.
For my flutter setup I need to run a stationary simulation first. This was done successfully. Here comes my problem: I want to perform the flutter case with ONLY the rotor part. Naturally, there is an interface region between vane and blade row because of pitch change and reference frame change. So I can easily extract pressure and temperature profiles here to use them as inlet bc for the rotor domain in flutter simulation. Unfortunately, I haven't found a way to introduce a surface at which I can cut the mesh for the flutter simulation.
A potential workaround would be to completely model with 3 separate domains, but then I have no idea on how to get the diffusor meshed w/o it containing a blade. Any suggestions?

Oh wow, we found the error. This can be closed.

In turbogrid rotor mesh file under mesh data, there is an on-off switch for each inlet and outlet domain. Enabling outlet domain there and moving the "fully extend" choice in Geometry->Outlet to something else, a surface can be set at which rotor and outlet domain are split and meshed separately.
