The Outlet, Interface node adds an outflow condition to the exterior interfaces of a layered shell.
Set the interfaces for which the outflow should be specified. Note that the Outlet, Interface node can only be applied to exterior interfaces of the layered shell. The settings are the same as for the
Interface Selection section of the
Mass Flux, Interface node.
The available Boundary Condition options for an outlet are
Velocity and
Pressure. After selecting a boundary condition from the list, a section with the same or a similar name displays underneath. For example, if
Velocity is selected, a
Velocity section, where further settings are defined, is displayed.
Enter a value or expression for the Normal outflow velocity U0 (SI unit: m/s). It is specified as
u =
nU0, so a positive value of
U0 represents an outflow velocity whereas a negative value represents an inflow velocity.
