calc_parallel_vectors() [1/3]

template<typename Real , typename GetV , typename GetW , typename XDomain , typename YDomain , typename ZDomain , invocable< Vec3< Real > >... Preds>

auto tatooine::detail::calc_parallel_vectors	(	GetV &&	getv,
		GetW &&	getw,
		tatooine::rectilinear_grid< XDomain, YDomain, ZDomain > const &	g,
		execution_policy::parallel_t const	policy,
		Preds &&...	preds
	)		-> std::vector<Line3<Real>>

Framework for calculating PV Operator.

Parameters

getv	function for getting value for V field
getw	function for getting value for W field

The algorithm processes z-slabs in parallel. For each slab all constant x-faces, all constant y-faces and all faces of each inner cube's tetrahedron are stored in a 2-D arrays. To be able to compute the cells of the grid both sides of the constant z-faces are needed. These are being stored ping-pong-wise.

calc_parallel_vectors() [2/3]

template<typename Real , typename GetV , typename GetW , typename XDomain , typename YDomain , typename ZDomain , invocable< Vec3< Real > >... Preds>

auto tatooine::detail::calc_parallel_vectors	(	GetV &&	getv,
		GetW &&	getw,
		tatooine::rectilinear_grid< XDomain, YDomain, ZDomain > const &	g,

		Preds &&...	preds
	)
