The dynamic boundary condition
ensures that the pressure on the cavity is constant and equal to the vapor pressure.
Two boundary conditions must be imposed on the free surface, namely the kinematic boundary condition and the dynamic boundary condition.
The dynamic boundary condition describes the continuity of the stress at the free surface, i.
Differential operators in the solution structures transmit information about the dynamic boundary conditions
from the boundary to the domain.
required software should perform periodic calculation of the dynamic boundary conditions
which are the actual parameters of the district heating network retrieved from the telemetry system.
In the interface-tracking methods, the free surface is treated as a boundary of the computational domain, where the kinematic and dynamic boundary conditions
