Hi all!

I found a strange behaviour for turbFoam and rhoTurbFoam - when i increase/decrease mesh size - the pressure range increases/decreases too... I can"t explain this...

PLEASE, HELP ME!

Matvej, could it concerns with volume averaging ? Did you compare - using ParaView - p(-volumeAveraged-, as ParaView print under the coloure scale of measure) & p(-from cell-) ?

I'm not sure, i'm understanding You...

Here are my steps:

blockMesh . .
rhoTurbFoam . .
paraFoam . .

In ParaView panel "Information" we have entry for:
+ volInterpolate(p) - interpolated values of pressure fieldd in cells
+ cell(p) - discreete values of pressure in cells

So, boundary values of discreete pressure field and interpolated pressure field are the same?

where i'm wrong?
