Constructor & Destructor Documentation

RoundCells() [1/2]

RoundCells::RoundCells	(	const PointMotion &	pm,
		const EquationOfState &	eos,
		OuterBoundary const &	outer,
		double	chi = 0.15,
		double	eta = 0.02,
		bool	cold = false,
		double	cold_speed = 0.15
	)

Class constructor.

Parameters

pm	Base point motion
eos	Equation of state
outer	The outer boudnary conditions, used for preventing points from getting outside the box. If periodic then no fix is applied
chi	chi parameter in equation 63
eta	eta parameter in equation 63
cold	Switch for cold flows
