forEachParticlePair()

template<typename Selector , typename Accessor , typename Func , typename... Args>

void walberla::mesa_pd::data::LinkedCells::forEachParticlePair ( const bool openmp, const Selector & selector, Accessor & acForLC, Func && func, Args &&... args ) const

inline

Calls the provided functor func for all particle pairs.

Additional arguments can be provided. No pairs with twice the same particle. Call syntax for the provided functor

func( *this, i, j, std::forward<Args>(args)... );

Parameters

openmp

enables/disables OpenMP parallelization of the kernel call

< current cell index

< current particle index

< particle to be checked against

< neighbor particle index

< neighbor cell index

< neighbor particle index

< neighbor particle index

forEachParticlePairHalf()

template<typename Selector , typename Accessor , typename Func , typename... Args>

void walberla::mesa_pd::data::LinkedCells::forEachParticlePairHalf ( const bool openmp, const Selector & selector, Accessor & acForLC, Func && func, Args &&... args ) const

inline

Calls the provided functor func for all particle pairs.

Additional arguments can be provided. No pairs with twice the same particle are generated. No pair is called twice! Call syntax for the provided functor

func( *this, i, j, std::forward<Args>(args)... );

Parameters

openmp

enables/disables OpenMP parallelization of the kernel call

< current cell index

< current particle index

< particle to be checked against

< neighbor particle index

< neighbor cell index

< neighbor particle index

< neighbor particle index
