boundary conditions
 

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?

Re: boundary conditions
 

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.
