compressible flow boundary conditions

I have a grid fin(just like a honeycomb structure) placed in the centre of a computational domain(a rectanglar box). all the data i have is free stream pressure(8325 pascal),free stream temperature(137k) and mach no(2.5)

Can anybody please help me with what boundary conditions i should use.

thanking in advance, ravi

Re: compressible flow boundary conditions
pressure-far-field might work

Re: compressible flow boundary conditions
thank you jehanzeb for the reply. pressure farfield, i have tried and its fine for the outer boundary i.e for computational domain.

what about inner boundary i.e for the grid fin, what boundary conditions should be given.

One more thing i want to ask is free stream pressure be considered as gauge or total or absolute pressure?

thanking you ravi
