Function Documentation

◆ adapt() [1/2]

void crv::adapt ( const ma::Input * in )

crv adapt with custom configuration

see maInput.h for details. note that this function will delete the Input object

◆ adapt() [2/2]

void crv::adapt ( ma::Input * in )

crv adapt with custom configuration

see maInput.h for details. note that this function will delete the Input object

◆ checkValidity()

int crv::checkValidity	(	apf::Mesh *	m,
		apf::MeshEntity *	e,
		int	algorithm = `2`
	)

checks validity of it and returns integer corresponding to invalid entity. Quality::checkValidity should be used if multiple elements checked in a row

Use an integer to determine the vuality tag 0 -> Not checked 1 -> Okay Quality 2-7 -> Vertex of index+2 is bad 8-13 -> Edge of index+6 is bad 14-17 -> Face of index+12 bad 20 -> Tet itself is bad, this one is the worst

6*dim + 2 + index

◆ getBezier()

apf::FieldShape* crv::getBezier ( int order )

Get the Bezier Curve or Shape of some order.

goes from first to sixth order

◆ interpolationError()

double crv::interpolationError	(	apf::Mesh *	m,
		apf::MeshEntity *	e,
		int	n
	)

computes interpolation error of a curved entity on a mesh

this computes the Hausdorff distance by sampling n points per dimension of the entity through uniform sampling locations in parameter space

◆ stats()

void crv::stats	(	ma::Input *	in,
		std::vector< double > &	edgeLengths,
		std::vector< double > &	linearQualities,
		std::vector< double > &	curvedQualities,
		bool	inMetric = `true`
	)

crv stats to get statistic information about the mesh

statistic considered are (1)final/desired edge-lengths (2) linear quality (3) curved quality (minJ/maxJ)
