Calculate velocity ratio
 

Hi All,

I would like to plot a contour of the velocity ratio throughout my domain between two different heights, say between z = 2m and z = 10m, i.e.

VR = V(z=2m)/V(z=10m)

Is there any way to do this within Fluent? I considered trying to use a custom field function, though it doesn't seem to me that there is a capability within Fluent to do this between two different locations. Solution using either Fluent or CFD-Post would be much appreciated! Thank you!

Please make a sketch, your description is not clear for me

Best regards
