Help：When buoyancy is activated, the pressure calculated by the solver excludes the hydrostatic pressure gradient. This modified pressure is often called motion pressure because it is responsible for driving the flow. All initial conditions and boundary conditions are interpreted in terms of this modified pressure.
If i models the dispersion of air bubbles in water in a rectangular bubble column,i set the water density as reference density,the interface Y0 as the reference position. When defining the initial pressure, I am confused.
How should i define the initial pressure distribution.
