gsHBoxUtils< d, T > Struct Template Reference

Detailed Description

template<short_t d, class T>
struct gismo::gsHBoxUtils< d, T >

The gsHBoxUtils provide basic utilities to modify HBoxes.

The gsHBoxUtils work on gsHBox objects and gsHBoxContainer objects. Other containers such as the gsHBox::Container (a vector of gsHBox) or gsHBox::SortedContainer can also be used. The gsHBox::HContainer is a container that stores gsHBox per level.

Template Parameters

d	Domain dimension
T	Real type

Static Public Member Functions
static gsHBox< d, T >::Container	ExactIntersection (const Container &container1, const Container &container2)
	Performs an intersection; only keeps the boxes that are EXACTLY the same (also level is the same)
static gsHBox< d, T >::Container	Intersection (const Container &container1, const Container &container2)
	Performs an intersection. Keeps the smallest boxes in overlapping regions, can also intersect partial boxes.
template<gsHNeighborhood _mode>
static HContainer	markAdmissible (const gsHBox< d, T > &marked, index_t m)
	Performs H-admissible refinement.
static HContainer	markHadmissible (const gsHBox< d, T > &marked, index_t m)
	Performs H-admissible refinement.
static HContainer	markHadmissible (const HContainer &marked, index_t m)
	Performs H-admissible refinement.
static HContainer	markTadmissible (const gsHBox< d, T > &marked, index_t m)
	Performs T-admissible refinement.
static HContainer	markTadmissible (const HContainer &marked, index_t m)
	Performs T-admissible refinement.
static Container	toContainer (const HContainer &container)
	Returns a container representation of the object.
static Container	toUnitBoxes (const HContainer &container)
	Transforms the boxes in container as unit boxes.
static HContainer	toUnitHBoxes (const HContainer &container)
	Transforms the boxes in container as unit boxes.
