Member Function Documentation

◆ findAll() [1/2]

template<typename TDerived >
virtual Size FinderTemplate< TDerived >::findAll ( const Size  index,
const Float  radius,
Array< NeighbourRecord > &  neighbours 
) const
inlineoverridevirtual

Finds all neighbours within given radius from the point given by index.

Point view passed in build must not be invalidated, in particular the number of particles must not change before function findAll is called. Note that the particle itself (index-th particle) is also included in the list of neighbours.

Parameters
indexIndex of queried particle in the view given in build function.
radiusRadius in which the neighbours are searched. Must be a positive value.
neighboursOutput parameter, containing the list of neighbours as indices to the array. The array is cleared by the function.
Returns
The number of located neighbours.

Implements IBasicFinder.

◆ findAll() [2/2]

template<typename TDerived >
virtual Size FinderTemplate< TDerived >::findAll ( const Vector pos,
const Float  radius,
Array< NeighbourRecord > &  neighbours 
) const
inlineoverridevirtual

Finds all points within given radius from given position.

The position may not correspond to any point.

Implements IBasicFinder.

Definition at line 147 of file NeighbourFinder.h.

◆ findLowerRank()

template<typename TDerived >
virtual Size FinderTemplate< TDerived >::findLowerRank ( const Size  index,
const Float  radius,
Array< NeighbourRecord > &  neighbours 
) const
inlineoverridevirtual

Finds all points within radius that have a lower rank in smoothing length.

The sorting of particles with equal smoothing length is not specified, but it is ensured that all found neighbours will not find the queries particle if findAsymmetric is called with that particle. Note that this does NOT find the queried particle itself.

Parameters
indexIndex of queried particle in the view given in build function.
radiusRadius in which the neighbours are searched. Must be a positive value.
neighboursOutput parameter, containing the list of neighbours as indices to the array. The array is cleared by the function.
Returns
The number of located neighbours. Can be zero.

Implements ISymmetricFinder.
