get_pairs()

std::vector< std::pair< int, int > > get_pairs	(	System::System const &	system,

Get pairs closer than distance from the cells.

Pairs are sorted so that first.id < second.id

get_pairs_filtered()

template<class Filter >

static auto get_pairs_filtered ( System::System const &  system, double const  distance, Filter  filter  )

static

Get pairs of particles that are closer than a distance and fulfill a filter criterion.

It uses link_cell to get pairs out of the cellsystem by a simple distance criterion and applies the filter on both particles.

Pairs are sorted so that first.id < second.id

Get pairs closer than distance if both their types are in types.

Pairs are sorted so that first.id < second.id
