Classes
struct	peclet::amr::PressureStagePolicy
	Which stage the distributed pressure ladder uses where its in-place lift blocks (docs/amr_mg_depth.md §5.6, WO4b; docs/amr_mg_core_boundary.md §11.1, §9.6, §9.7). More...
struct	peclet::amr::MgLevelPrediction< Dim >
	One predicted level of the pressure ladder (docs/amr_mg_depth.md §6.7). More...
struct	peclet::amr::MgLadderPrediction< Dim >
	The whole predicted ladder: what predictPressureLadder returns and what peclet.amr.predict_hierarchy hands to Python as a dict. More...

Enumerations
enum class	peclet::amr::MgLevelKind {   peclet::amr::Octree , peclet::amr::Lifted , peclet::amr::Tail , peclet::amr::Sibling ,   peclet::amr::Repartition }
	Where a predicted level comes from. More...
enum class	peclet::amr::MgBottomKind { peclet::amr::Jacobi , peclet::amr::Amg }
	What solves the coarsest level. More...

Functions
template<int Dim>
bool	peclet::amr::amrStageLiftable (const core::decomp::BlockDecomposer< Dim > &dec)
	amr's lift rule (docs/amr_mg_depth.md §6.2) as core's stage predicate: the level grid halves into a cube level with at least two cells per axis, and every block is even in origin and size on EVERY axis.
const char *	peclet::amr::toString (MgLevelKind k)
const char *	peclet::amr::toString (MgBottomKind k)
template<int Dim>
Index	peclet::amr::detail::maxExtent (const IVec< Dim > &G)
template<int Dim>
bool	peclet::amr::detail::gridCanHalve (const IVec< Dim > &G, Index bottomExtent)
	The grid half of the §6.2 rule: stop when the bottom smoother is already exact, and when the grid cannot halve into a cube level with at least two cells per axis.
template<int Dim>
long long	peclet::amr::detail::cellsOf (const IVec< Dim > &G)
template<int Dim>
void	peclet::amr::detail::pushLevel (MgLadderPrediction< Dim > &p, const IVec< Dim > &G, MgLevelKind kind)
template<int Dim>
MgLadderPrediction< Dim >	peclet::amr::predictPressureLadder (IVec< Dim > G, unsigned lmax, int numRanks, Index bottomExtent=4, const PressureStagePolicy &policy={})
	Predict the pressure-multigrid ladder for a global ROOT grid G (in root cells, i.e.
