Detailed Description

Array of struct enumerator.

This is the default enumerator for all DoFs in ExaHyPE 2.

We assume that we have a lexicographic ordering of the cell data or DG degree of freedom (quadrature points) and all data therein are ordered lexicographically and stored in as AoS: All data are

organised as array of structs, i.e. if you store quantities (a,b,c) per degree of freedom (dof), then the array first holds the a value of the first dof, then the b value, then the c value, and then it continues with the a value of the next dof.
organised lexicographically, i.e. we first enumerate all the degrees of freedom along the x-axis, then along the y-axis, then along the z-axis.
organised from left to right, bottom-up and front to back.
organised one cell after another, i.e. we first enumerate all the values of the first cell, before we continue with any value of the second cell.

See also: enumerator.h for a generic description of attribute semantics.

Parameters

numberOfCells	The cells are enumerated one after another, i.e., we work with an array of cells hosting arrays of structs.
haloSize	Number of dofs around the cell which do not carry active information, i.e., data you write to.
