Pressure Point Constraint
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.
Pressure Constraint
The relative pressure value is set by specifying the Pressure p0. If the reference pressure pref defined at the physics interface level is equal to zero, p0 represents the absolute pressure.

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.
