Hi,

It should not be very different from the airfoil tutorial.

You will have to choose boundaries far enough for them to assumed as farfield, you can specify the pressure at this boundary.

The other two bocos will probably be velocity inlet and pressure outlet.

I would recommend structured meshing if you want to extract drag from your simulation.
