'cell relative: velocity magnitude' vs 'velocity magnitude'

alpharays · October 1, 2014, 02:12

Hi,

What is different between 'cell relative: velocity magnitude' vs 'velocity magnitude'?

In star ccm+, why we should use 'cell relative: velocity magnitude' to plot surface contour for velocity?

Thanks

Hm !? Eleven posts and a reputation power of 5. You should be a real cfd expert. And now such a question?

"Cell relative velocity magnitude" ignores that the velocity at the wall is zero and shows you the "near wall velocity".

Hi

Will be really great if someone could post a link to documentation on Cell Relative Velocity.

Thanks in Advance
