The Inlet, Interface node adds an inflow condition to the exterior interfaces of a layered shell.
Set the interfaces for which the inflow should be specified. Note that the Inlet, 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 inlet are
Velocity,
Pressure, and
Mass flow. 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 inflow velocity U0 (SI unit: m/s). It is specified as
u =
−nU0, where
n is the face normal and
U0 is the normal inflow speed. A positive value of
U0 represents an inflow velocity. A negative value represents an outflow velocity.
If you select Mass flow as the inlet condition, you have to specify the
Mass flow type, either as total
Mass flow rate M0 (SI unit: kg/s), or the
Pointwise mass flux N0 (SI unit: kg/(m
2·s)).
With Mass flow rate boundary interface condition, positive values correspond to flow into the shell:
where M0 is a value or expression for the specified inward (or outward) Darcy flux.
For the Pointwise mass flux boundary interface condition, positive values correspond to flow into the shell:
where N0 is a value or expression for the specified inward (or outward) Darcy flux.
