If Pressure is Static, and the reference pressure pref, defined at the physics interface level, is equal to 0, the value of the pressure p0, at the boundary, is the absolute pressure. Otherwise, p0 is the relative pressure at the boundary.

If Pressure is Total, the Average check box is available and unselected by default to prescribe the total pressure pointwise. If it is selected, the averaged total pressure is imposed in the weak forms instead.

The Suppress backflow option adjusts the inlet pressure locally in order to reduce the amount of fluid exiting the domain through the boundary. If you clear the suppress backflow option, the inlet boundary can become an outlet depending on the pressure field in the rest of the domain.

Flow direction controls in which direction the fluid enters the domain.

For Normal flow, it prescribes zero tangential velocity component.

For User defined, an Inflow velocity direction du (dimensionless) should be specified. The magnitude of du does not matter, only the direction. du must point into the domain.
