I have two configurations of the same model. The model is an airplane with a propeller.
The first configuration has just the propeller enabled in a rotating region (a cylinder) and a very fine mesh (the rest of the geometry is disabled in configuration control).
The second configuration has the propeller geometry disabled and the airplane geometry enabled, and I transferred the boundary condition from the cylinder surrounding the propeller in the other case. I used the 'ambient' case type of transferred boundary condition because I want to transfer pressures and velocity components.
When I solve the second case, I get a warning "Unresolved Boundary Condition - Transferred Boundary Condition".
I assume that's bad... but... what does it mean, and how to I resolve it?
