◆ CartesianDerivIterator

template<unsigned int NCenters>

Enumeration Type Documentation

◆ BraKet

enum class libint2::BraKet

strong

types of shell sets supported by Engine, in chemist notation (i.e.

'_' separates particles)

Warning: macro BOOST_PP_NBODY_BRAKET_RANK_TUPLE include the ranks of all brakets in BraKet and macro BOOST_PP_NBODY_BRAKET_MAX_INDEX must be equal to the max value in this enum

◆ ScreeningMethod

enum class libint2::ScreeningMethod

strong

describes method for primitive screening used by ShellPair and Engine

Note

Rationale. Since Engine::compute2() can compute primitive data on-the-fly it needs cheap methods for screening primitives.

ScreeningMethod::Original was the fast approach that works well for uncontracted integrals over spherical (L=0) Gaussians, but can introduce significant errors in integrals over nonspherical and contracted Gaussians.
ScreeningMethod::Conservative addresses the weaknesses of the original method and works well across the board.
ScreeningMethod::Schwarz and ScreeningMethod::SchwarzInf should be used when it is possible to precompute the shell pair data and the data can be computed for a specific operator type. These approaches provide rigorous guarantees of precision.
