Wrong pressure Field?
 
Hi all,

I'm working on a flow around a cone with interFoam. It appears that the pressure boundary condition on my cone creates an ascendant velocity field, whereas I have theorically no movement.

I tried with buoyantPressure and uniformDensityHydrostaticPressure, and both gave me this results. Zerogradient can't be use because it doesn't respect mass conservation.

I use a Spalart Allmaras LES turbulence model, and U is set to slip on every boundary condition.

If someone has any idea, it woult be great!

Regards

Hi Julien,
I have a similar problem. Did you solve this problem?
