Hi, everyone,
I'm using CFX to solve my case and CFD-post to do the post-process.
In my simulation, the domain is rotating and the wall is stationary relative to the domain. Theoretically, the relative velocity should be 0 throughout the wall, and the velocity contour confirms this. however, when I output the velocity value on the wall, I found that all the velocity values are not zero. This really bothers me a lot.
It would really help me a lot if anyone could explain the reason.
Thanks a lot!


Sorry I have problem attaching any figure.

Thank you ghorrocks.

I think i should check the FAQ first next time
