Hi..

I am using Fluent 13.0 version. I also had an experience of using Fluent 6.3 version.
I see a change in 13.0 version. In earlier version i.e. Fluent 6.3, the input required under velocity boundary condition are velocity magnitude and direction or velocity components etc. Nothing required for pressure.
But Fluent 13.0 also asked for supersonic/initial gauge pressure.

I am confused what value should I enter here..Fluent 13.0.jpg

The two pictures are for velocity inlet for laminar and turbulent models. And they are same in fluent 6 and fluent 13.
