Public Member Functions
constexpr	Row_index (int nd, int rs, int id)
constexpr void	operator++ ()
	advances object to the next row
constexpr	operator bool () const
	returns true if object is pointing to a valid row and false if it is pointing past the last row
constexpr int	i_face_qpoint () const
	returns the index of the row (or equivalently the face quadrature point) the object is pointing to
constexpr int	i_qpoint (int i_node) const
	returns the index (with respect to the entire quadrature point array) of the i_nodeth quadrature point in the current row
constexpr int	i_node (int i_qpoint) const
	returns the index of a quadrature point in its own row, i.e. which Basis::node it is

Public Attributes
const int	n_dim
const int	row_size
const int	i_dim
const int	n_qpoint
	how many total quadrature points an element has
const int	n_fqpoint
	how many quadrature points the face of an element has
const int	stride
	the stride required to step through the row

Detailed Description

Facilitates the process of iterating through all rows along a particular dimension.

This is essential in the local kernel where a row_size[xrow_size[xrow_size]] array of flux values must be multipled by the derivative matrix row-wise along every dimension.

Constructor & Destructor Documentation

Row_index()

hexed::Row_index::Row_index ( int nd, int rs, int id )

inlineconstexpr

constructs a Row_index in nd dimensions, with row size rs, and applicable to rows in the idth dimension. Object is initialized to point to the first row.

Member Function Documentation

i_node()

int hexed::Row_index::i_node ( int i_qpoint ) const

inlineconstexpr

returns the index of a quadrature point in its own row, i.e. which Basis::node it is

always gives the same value regardless of which i_face_qpoint() this object is pointing to
