Cell volume Change was the metric was asking and not the cell volume itself. In order to summarize here:


 


1/You see a finite value of siwrl velocity at axis which is not physical. This appears with RSM and not with two-equation models


2/You see that 2D and 3D


Is this correct?


What is the boundary condition you provide at your inlet in 2D/3D?
