cfd-star Guest Posts: n/a	Dear Cfd people, I am trying to model the flow around a helicopter hull including blades. Is there anyone who tried a similar simulation before? The main problem is that I couldn't specify a BC at the rotor blades. I thouht that it suffices providing an inlet BC (assuming the rotor blades as a spinning disc) specifying the velocity at the rotor blades. Although Flow is rotational around the blades, I thought computing an initial guess with specified inlet condition will work?
