The mass flow boundary (and if it's constant density use a velocity bc) has direction vector options as you've seen. The component values are for you to decide, but for swirl I'd tend to favour axial and angular components over axial and tangential. Tangential velocity would need a profile whilst angular may be constant over the radial profile.Â
