Default outflow boudary condition

hello,

Why is the outflow boudary condition inappropriate for compressible flow ? In my problem, this condition seems good but the fluid is compressible. Could you help me?

Thanks

If you want to use outflow BC, you must sure that flow is really out of your domain that means no reverse flow happened.

If I am sure of no reverse flow but at the exit flow is supersonic compressible, is it a right choice in this situation, if no then anyother suggestion, thanks

No, you can only use pressure outlet for compressible flow simulations.

In external flow problems like flow over an aerfoil or on a cone usually before hand one is not known of pressure or velocity at the outlets, then how to use that pressure condition (for the case when I want to take outlet condition exactly at the body end)
