K-epsilon Model
 

Hello everybody!
I have built a mesh (see pics) to simulate a wind tunnel test of a simple building.
I need to represent the boundary layer and the mesh has a y+ value close to 1 (of course, it depends on the solution).
The grow rate is 1.2 .

Running a simple k-epsilon model in Fluent:

- THE PRESSURES ON THE WALLS ENDS TO BE COSTANT AND = 0 !!!

Moreover..

- gives me reverse flow at the beginning, but it disappear before the end
- gives me warnings on the value of the viscosity (it is too big, but it keeps on iterating)

Any suggestion?

I hope it is clear,
thanks a lot,

Fabio

there are no pics attached

ops... thanks!
