Function Documentation

apf::Field* spr::getGradIPField	(	apf::Field *	f,
		const char *	name,
		int	order
	)

compute the gradient of a vector or scalar field at integration points

Parameters

f	(In) scalar or vector nodal field
name	(In) name of integration point field
order	(In) integration order of accuracy

apf::Field* spr::getSPRSizeField	(	apf::Field *	f,
		double	adapt_ratio
	)

run the SPR ZZ error estimator

Parameters

f	the integration-point input field
adapt_ratio	the fraction of allowable error, scales the output size field.

apf::Field* spr::getTargetSPRSizeField	(	apf::Field *	f,
		size_t	t,
		double	alpha = `0.25`,
		double	beta = `2.0`
	)

run the SPR ZZ error estimator with a target # of output elems

Parameters

f	the integration-point input field
t	the target number of output elements after adaptation
alpha	floor on the size field; alpha < h_new/h_old < beta
beta	ceiling on the size field; alpha < h_new/h_old < beta

apf::Field* spr::recoverField ( apf::Field * ip_field )

recover a nodal field using patch recovery

Parameters

ip_field (In) integration point field
