I am working on a low speed free jet simulation, but I am not sure how to define the boundary conditions. Inlet and pressure for the outlet region is clear but I've no idea how to handle the "surrounding walls". I think I need a sort of "free stream" for incompressible flows but this is not available in STAR. Any suggestions what I can do?

Thx

You can use pressure boundary condition with environmental option
