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 |
