◆ get_move_vectors()

map< int, Vec3 > Frac::get_move_vectors ( const Graph & g )

private

calculate the vectors for "exploding" the grain -> get centers of the new fragment

Parameters

g	the graph from which the positions are taken

int Frac::writeAllMass	(	ostream &	ost,
		double	minmass,
		int	count,
		bool	with_tag = `false`
	)

write out all fragment masses

◆ writeAsVtk()

void Frac::writeAsVtk	(	const string &	basefilename,
		float	exp,
		const Graph &	g_new,
		bool	fakevec
	)

output fractured particles as VTK-XML files. The particles are "exploded", i.e. the fragments are moved out from the center for better visibility.

Parameters

basefilename	the base filename, i.e. the files will be called basfilename.0.xml, basefilename.1.xml...
exp	the relative amount by which the new fragments are moved
g_new
fakevec
