Detailed Description

Correction to point velocities that keeps cells round.

Based on Philip Mocz method

Definition at line 18 of file CentroidMotion.hpp.

Constructor & Destructor Documentation

CentroidMotion::CentroidMotion	(	PointMotion const &	bpm,
		double	reduction_factor,
		EquationOfState const &	eos,
		size_t	niter = `2`,
		vector< string >	toignore = `vector<string>()`
	)

Class constructor.

Parameters

bpm	class of point motion on which to apply the fix
reduction_factor	The factor to reduce the correction velocity (1/reduction_factor is the number of iterations to fix)
niter	The number of correction iterations to apply
eos	The equation of state
toignore	List of sticker names not to apply correction for
