Detailed Description

template<class ParticleCell, class PairwiseFunctor>
class autopas::VCLC06Traversal< ParticleCell, PairwiseFunctor >

A traversal for VerletClusterLists that uses a coloring over the grids of the container.

The traversal uses a 2D coloring with a stride of x=3, y=2, so 3*2=6 colors.

When disabling newton 3, interactions inside a cluster are still calculated using newton 3.

Template Parameters

ParticleCell
PairwiseFunctor

Member Function Documentation

◆ endTraversal()

template<class ParticleCell , class PairwiseFunctor >

void autopas::VCLC06Traversal< ParticleCell, PairwiseFunctor >::endTraversal ( )

inlineoverridevirtual

Finalizes the traversal.

Should be called after traverse().

Implements autopas::TraversalInterface.

◆ getTraversalType()

template<class ParticleCell , class PairwiseFunctor >

TraversalOption autopas::VCLC06Traversal< ParticleCell, PairwiseFunctor >::getTraversalType ( ) const

inlineoverridevirtual

Return a enum representing the name of the traversal class.

Returns: Enum representing traversal.

Implements autopas::TraversalInterface.

◆ initTraversal()

template<class ParticleCell , class PairwiseFunctor >

void autopas::VCLC06Traversal< ParticleCell, PairwiseFunctor >::initTraversal ( )

inlineoverridevirtual

Initializes the traversal.

Should be called before traverse().

Implements autopas::TraversalInterface.

◆ isApplicable()

template<class ParticleCell , class PairwiseFunctor >

bool autopas::VCLC06Traversal< ParticleCell, PairwiseFunctor >::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 >

void autopas::VCLC06Traversal< ParticleCell, PairwiseFunctor >::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 >

void autopas::VCLC06Traversal< ParticleCell, PairwiseFunctor >::traverseParticles ( )

inlineoverridevirtual

Traverse the particles by pairs, triplets etc.

as determined by the Functor type.

Implements autopas::TraversalInterface.
