Enumerations
enum	peclet::core::amr::AdaptFlag : int { peclet::core::amr::kCoarsen = -1 , peclet::core::amr::kKeep = 0 , peclet::core::amr::kRefine = 1 }
	Per-leaf adaptation flags from an indicator: refine where ind > refineThresh (and the leaf can go finer, level > finestLevel), coarsen where ind < coarsenThresh (and it can go coarser, level < lmax), else keep. More...

Functions
double	peclet::core::amr::detail::minmod (double a, double b)
template<int Dim, unsigned Bits>
std::vector< double >	peclet::core::amr::transferField (const BlockOctree< Dim, Bits > &oldT, const std::vector< double > &oldF, const BlockOctree< Dim, Bits > &newT, bool linear=true)
	Conservative remap of a leaf field from oldT to newT (same domain).
template<int Dim, unsigned Bits>
std::vector< int >	peclet::core::amr::flagByIndicator (const BlockOctree< Dim, Bits > &t, const std::vector< double > &ind, double refineThresh, double coarsenThresh, unsigned finestLevel=0)
template<int Dim, unsigned Bits>
AdaptResult< Dim, Bits >	peclet::core::amr::adaptField (const BlockOctree< Dim, Bits > &t, const std::vector< double > &f, const std::vector< int > &flags, bool linear=true)
	Apply adaptation flags (one level of refine/coarsen) to t carrying field f, then 2:1-balance and remap.
template<int Dim, unsigned Bits>
AdaptResult< Dim, Bits >	peclet::core::amr::adapt (const BlockOctree< Dim, Bits > &t, const std::vector< double > &f, double refineThresh, double coarsenThresh, unsigned finestLevel=0, double eps=0.01, bool linear=true)
	All-in-one solution-adaptive step: Löhner indicator → flags → adaptField.
