Dendro  5.01
Dendro in Greek language means tree. The Dendro library is a large scale (262K cores on ORNL's Titan) distributed memory adaptive octree framework. The main goal of Dendro is to perform large scale multiphysics simulations efficeiently in mordern supercomputers. Dendro consists of efficient parallel data structures and algorithms to perform variational ( finite element) methods and finite difference mthods on 2:1 balanced arbitary adaptive octrees which enables the users to perform simulations raning from black holes (binary black hole mergers) to blood flow in human body, where applications ranging from relativity, astrophysics to biomedical engineering.
idx

Computes the overlapping nodes between given two elements. Note that idx ,idy, idz should be integer array size of (m_uiElementOrder + 1).

Parameters
[in]Parent: denotes the larger(ancestor) element of the two considering elements.
[in]child: denotes the desendent from the parent element.
[out]idxmapping between x nodes indecies of parent element to x node indecies for the child element.
[out]idymapping between y nodes indecies of parent element to y node indecies for the child element.
[out]idzmapping between z nodes indecies of parent element to z node indecies for the child element. [0]= 2 implies that the parent element x index 0 is given from the child x index 2.
