why is my incompressible flow simulation dependent on the free stream velocity ?
 

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.

Thanks a lot for the reply.
