Hi guys,

I know that for subsonic inflow you would normally only impose two flow properties and let the third one be calculated. However, in my case I know the exact conditions of the flow at my inflow boundary condition.

So is it a valid approach to simply impose everything at the subsonic inflow with a Dirichlet BC?

Cheers!

No, you can't match the exact condition with the numerical solution. You need to let from the interior
