subroutine interpolation::buildquadranttree	(	type(mesh_t)	Mesh,
		real(kind=dp), dimension(6)	BoundingBox,
		type(quadrant_t), pointer	RootQuadrant
	)

Builds a tree hierarchy recursively bisectioning the geometry bounding box, and partitioning the bulk elements in the last level of the tree hierarchy.

Parameters

mesh	Finite elememt mesh
boundingbox	XMin, YMin, ZMin, XMax, YMax, ZMax
rootquadrant	Quadrant tree structure root

Checks whether a given point belongs to a given bulk element If it does, returns the local coordinates in the bulk element.

Parameters

element	Bulk element we are checking
elementnodes	The nodal points of the bulk element
point	Point under study.
localcoordinates	Local coordinates corresponding to the global ones.
globaleps	Required accuracy of global coordinates
localeps	Required accuracy of local coordinates
numericeps	Accuracy of numberical operations
globaldistance	Returns the distance from the element in global coordinates.
localdistance	Returns the distance from the element in local coordinates.
