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	SetFluidProperties
	Class SetFluidProperties is a utility class which sets the fluid and solid Eulerian density based on the current level set information. More...

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.
