negative RPM

Is it possible to specify a negative rpm in the multiple reference frame model. I am simulating a 3D rotor, the geometry etc is fine and when I specified a 70rpm value the flow path was very strange. I thought I had the rotation in the wrond direction so I just used -70 rpm but the results are now too low.

If I have a 3D rotor with the axis of rotation around z axis and origin 0,0,0 (x, y, z), looking topdown on this is the normal positive rotation clockwise or anticlockwise?

Thanks very much

Re: negative RPM
Negative rpm is acceptable in FLUENT.
