Hi,
I did a CFD simulation for an internal flow in SU2 using SST model. I have a uniform velocity at the inlet, no slip condition at the walls and constant pressure at the outlet. Then, I noticed something rather strange. The solution highly depends on the free stream velocity. Since I am prescribing everything at the inlet, I have no idea how the free stream velocity is influencing the solution. Any ideas? Thanks |

Hi Ryan,
this is a bug. The boundary conditions of the SST model are at the moment computed using the free stream velocity. We will solve that problem soon. Tim |
