Dear colleagues,

Did somebody ever meet a problem with correct specification of the X and Y velocity components in Fluent boundary conditions (lets say flow mass inlet)?
We have to put injection from a ramp surface at angle -180 degree (opposite to the x-axis direction). We specify x-velocity equal -1 and y-velocity to 0, and get wrong angles of the jet and wrong parameters (as Mach, temperature, etc.) at the boundary. If you have a glue what is going wrong, please, let me know!
