The vc_ins_utilities class can be utilized to set fluid properties such as density and viscosity for both two-phase and three-phase flows throughout the entire domain. Additionally, this class provides implementations for gravity force calculations in two-phase and three-phase flows. More...

Classes
class	GravityForcing
	The GravityForcing class provides an implementation of gravity force. This class can be utilized to apply the gravitational force \( \rho g \) using the density field, which includes all three phases: liquid, gas, and solid; or using the flow density field, which includes only liquid and gas phases and excludes the solid phase.
