Function Documentation

is_consistent()

bool internal::GridReordering2d::is_consistent

(

const std::vector< CellData< 2 > > &

cells

)

Check whether a given arrangement of cells is already consistent. If this is the case, then we skip the reordering pass.

This function works by looping over all cells, checking whether one of its faces already exists in a list of edges, and if it already exists in reverse order, then return false. If it is not already in the list, or in the correct direction, then go on with the next faces or cell.

quadside()

MSide internal::GridReordering2d::quadside	(	const CellData< 2 > &	q,
		unsigned int	i
	)

Returns an MSide corresponding to the specified side of a deal.II CellData<2> object.
