Hi all,

I am trying to perform a 2D analysis of an NREL S-833 airfoil with a varying pitch. I want to do steady-state RANS modelling, and vary the pitch using the Parameter Set while outputting the lift and drag coefficients for each design point.

I currently have my geometry as an airfoil subtracted from a circle which rotates inside of the larger geometry. The circular section is subjected to the "Rotate" body transformation, whose angle is set as one of the input parameters.

I have named selections for the inside and outside components of the circle to act as the interface, all of my other boundary conditions are named and defined, and all works well for the first simulation. Then, when the design study changes the blade pitch, it seems that it drops some of the named selections, giving this error:

Model information is incompatible with incoming mesh.Following zones were missing in the mesh:
body ,moving_interface-contact_region-trg
Following new zones were found in the mesh:
contact_region-trg ,wall-s-833-moving_surface-plane1

Is there a way that I can fix this dropping of zones such that the software can run through all of my design points? Or perhaps there is an easier way to accomplish this task?

I appreciate any input you can provide.
