Does anyone have any ideas how I might go about using surfaces on a volumetric control body as the input surface for a wake refinement mesh operation? Long story short, I have a rotorcraft modeled using the blade element virtual disk. The downwash from the rotor needs some refinement, but I am only able to select surfaces which are boundaries in my domain as input part for surface mesh operations.

I want to be able to use the volumetric control I used to set the mesh inside the rotor momentum source as the input for the wake mesh.

My backup plan is to either create a CAD body or use field function refinement, but those are a little more involved than what I felt was necessary for this situation.
