Detailed Description

Finder projecting a uniform grid on the particles.

Definition at line 14 of file UniformGrid.h.

Constructor & Destructor Documentation

◆ UniformGridFinder()

NAMESPACE_SPH_BEGIN UniformGridFinder::UniformGridFinder ( const Float relativeCellCnt = 1 )

Parameters

relativeCellCnt Multiplier of the number of constructed voxels. The actual number scales with the number points; relative voxel count 1 means that on average, one cell will contain one particle. Higher value means more cells, therefore less than one particle per cell, etc.

◆ ~UniformGridFinder()

UniformGridFinder::~UniformGridFinder ( )

default

Member Function Documentation

◆ buildImpl()

void UniformGridFinder::buildImpl	(	IScheduler &	scheduler,
		ArrayView< const Vector >	points
	)

overrideprotectedvirtual

Builds finder from set of vectors.

This must be called before findAll, can be called more than once.

Parameters

scheduler	Scheduler that can be used for parallelization.
points	View of the array of points in space.

Implements IBasicFinder.

◆ find()

template<bool FindAll>

		const Size	index,
		const Float	radius,
		Array< NeighbourRecord > &	neighs
	)		const

◆ getDimensionSize()

INLINE Size UniformGridFinder::getDimensionSize ( ) const

inline

Definition at line 52 of file UniformGrid.h.

◆ iterate()

template<typename TFunctor >

void UniformGridFinder::iterate ( const TFunctor & functor )

inline

Exposed for gravity

Todo:: refactor, finder shouldn't know anything about gravity
