Detailed Description

template<class ParticleCell, class PairwiseFunctor, class NeighborList>
class autopas::VLCC18Traversal< ParticleCell, PairwiseFunctor, NeighborList >

This class provides the lc_c18 traversal.

The traversal uses the c18 base step performed on every single cell. Since these steps overlap a domain coloring with eighteen colors is applied.

For each cell all neighbor lists are processed, so depending on whether lists were built with newton3 the base step is c01 or c18

Template Parameters

ParticleCell	the type of cells
PairwiseFunctor	The functor that defines the interaction of two particles.
NeighborList	type of the neighbor list

Member Function Documentation

◆ getTraversalType()

template<class ParticleCell , class PairwiseFunctor , class NeighborList >

TraversalOption autopas::VLCC18Traversal< ParticleCell, PairwiseFunctor, NeighborList >::getTraversalType ( ) const

inlineoverridevirtual

Return a enum representing the name of the traversal class.

Returns: Enum representing traversal.

Implements autopas::TraversalInterface.

◆ isApplicable()

template<class ParticleCell , class PairwiseFunctor , class NeighborList >

bool autopas::VLCC18Traversal< ParticleCell, PairwiseFunctor, NeighborList >::isApplicable ( ) const

inlineoverridevirtual

Checks if the traversal is applicable to the current state of the domain.

Returns: true iff the traversal can be applied.

Implements autopas::TraversalInterface.

◆ setSortingThreshold()

template<class ParticleCell , class PairwiseFunctor , class NeighborList >

void autopas::VLCC18Traversal< ParticleCell, PairwiseFunctor, NeighborList >::setSortingThreshold ( size_t sortingThreshold )

inlineoverridevirtual

Set the sorting-threshold for traversals that use the CellFunctor If the sum of the number of particles in two cells is greater or equal to that value, the CellFunctor creates a sorted view of the particles to avoid unnecessary distance checks.

Parameters

sortingThreshold Sum of the number of particles in two cells from which sorting should be enabled This traversal does not use the CellFunctor, so the function has no effect here

Implements autopas::CellTraversal< ParticleCell >.

◆ traverseParticles()

template<class ParticleCell , class PairwiseFunctor , class NeighborList >

void autopas::VLCC18Traversal< ParticleCell, PairwiseFunctor, NeighborList >::traverseParticles ( )

overridevirtual

Traverse the particles by pairs, triplets etc.

as determined by the Functor type.

Implements autopas::TraversalInterface.
