Hello to everybody.

Is Flow3d able to model an outlet of tunnel? The flow inside the tunnel

is pressurized, while after the outlet is unsubmerged.

In other hand, at the beginning of the mesh is possible to assign both

pressure ( height of the fluid ) and mean velocity?

Have you ever been this case?

Thanks in advance.

Hi,

You can't have both pressure and velocity at the same boundary. You can define fluid height and pressure OR velocity at the inlet. Regarding the downstream boundary, you could also set fluid height and pressure at the outlet to correspond to the free stream boundary condition.
