Detailed Description

Hexagonal close packing.

Member Enumeration Documentation

◆ Options

enum HexagonalPacking::Options

strong

Enumerator

SORTED

Particles are sorted using its Morton code.

    If used, particles close in space are also close in memory. Otherwise, particles are sorted along
    x axis, secondary along y and z axes.

CENTER

Move particle lattice so that their center of mass matches center of domain.

    This assumes all particles have the same mass. Note that with this options, generated particles
    does not have to be strictly inside given domain.

SPH5_COMPATIBILITY

Generates the grid to match code SPH5 for 1-1 comparison.

    Not that this will generate significantly more particles than requested (approximately by
    factor 1.4).

Member Function Documentation

◆ generate()

Array< Vector > HexagonalPacking::generate	(	IScheduler &	scheduler,
		const Size	n,
		const IDomain &	domain
	)		const

overridevirtual

Generates the requested number of particles in the domain.

Function shall also set the smoothing lenghts of the generated particles in the 4th components of the returned vectors.

Parameters

scheduler	Scheduler that can be used for parallelization.
n	Expected number of generated particles.
domain	Computational domain where the vertices are distributed

Returns: Output array of vertices. The total number of vertices can slightly differ from n.

Note: This method is expected to be called once at the beginning of the run, so we can return allocated array without worrying about performance costs here.

Implements IDistribution.
