Inlet
Use the Inlet node to define an edge or point where fluid enters the gap.
Inlet Settings
Select an Inlet condition — Zero pressure (the default), Pressure, or Normal inflow velocity. When the Cavitation check box is selected for the physics interface (see Cavitation), Starvation is also available.
•
For Zero pressure pf = 0 applies on the boundary, edge, or point.
•
For Pressure enter a Pressure pf0 (SI unit: Pa) to impose pf = pf0 on the boundary, edge, or point. The default is 0 Pa. 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 (SI unit: m/s). The default is 0 m/s.
•
For Starvation enter a value for the Fluid fraction θ0 (dimensionless). The default is 0.6.
