Inlet
Use the Inlet node to define an edge or a part of the boundary where fluid enters the gap.
Inlet Settings
For the Inlet node with edge selection, select an Inlet condition — Zero pressure, Pressure, or Normal inflow velocity.
When the Liquid with cavitation is selected in the physics interface, Starvation is also available.
•
For Zero pressure, pf = 0 applies on the edge.
•
For Pressure, enter a Pressure pf0 to impose pf = pf0 on the edge. If the reference pressure pref, defined at the physics interface level, is 0, pf0 is the absolute pressure. Otherwise, pf0 is the relative pressure.
•
For Normal inflow velocity, enter a Normal inflow velocity U0.
•
For Starvation, enter a value for the Fluid fraction θ0.
For the Inlet node with boundary selection, specify the Pressure at the inlet.
