how to set rotating boundary?
for example, air flows inside a 3D square channel, say x is flow direction, y,z are cross direction,the case is very simple. Now, the channel rotating with its axes, say y-axes, how to set rotating boundary?
if I have set "FLUID,moving frame, ratating velocuty, direction"
what is the difference in wall boundary between "staionary" and "movingwall,relative to adjacant cell zone, speed=0" ?
for this case, which option should I choose?

I'm stuck on the same thing. I'm trying to model a 3D rotating channel on FLUENT. I've tried using moving reference frame (MRF) as well as simple UDF to incorporate coriolis and centrifugal body forces, however I've been unable to validate my results with that of ASME and other papers...
