The Pressure Point Constraint condition can be used to specify the pressure level. If it is not possible to specify the pressure level using a boundary condition, the pressure level must be set in some other way, for example, by specifying a fixed pressure at a point.
The relative pressure value is set by specifying the Pressure p0. Or, if the reference pressure
pref defined at the physics interface level is equal to zero,
p0 represents the absolute pressure.
When Include gravity is selected and
Use reduced pressure not selected in the interface
Physical model section, the
Compensate for hydrostatic pressure approximation (named
Compensate for hydrostatic pressure for compressible flows) check box is available and selected by default. When it is selected, the hydrostatic pressure is automatically added to the pressure entered in
p0 user input.
The Apply reaction terms on setting is set per default to
Individual dependent variables.
All physics (symmetric) cannot be used together with a segregated solver when fluid flow is coupled with Moving Mesh, Level Set, or Phase Field.
