hey everybody, I'm in trouble with the boundary conditions. I have a vertical cylinder with 192m lenght, the inflow is at the ambiant pressure so i put pressure inlet 0, but the outlet is 192m hide from the grownd, so we have a depression of -2283 Pa, How can i say that to fluent?

your bottom of the cylinder should be defined as interior with pressure value given

tanks Gaurav Mehra, but the problem is how to put the depression value -2285 on a boundary condition.

thanks Gaurav Mehra, but the problem is how to put the depression value -2285 on a boundary condition.
