A rotating solid domain in CFX551?

rotlin

I'm trying to build a rotating solid domain, how can I do this? is it possible in CFX551?

I tried to build all in one mesh group, but I could not define the rotating part.

I tried to build two "mesh only" dbs, one for the rotating solid, one for the fluid. Then I built a mesh import db and defined a sub-solid domain, but when I tried to write the def file, a message "there are no fluid regions" popped up. If I delete the subdomain, then it's OK without a solid defined.

Could anyone help me to solve this problem or give me some suggestions? Thanks!

If it's not possible in CFX551, would it be implemented in 5.6? (if anyone knows.)
