Detailed Description

Filter to select particles that correspond to a z-slice of the corresponding lab-frame.

Constructor & Destructor Documentation

◆ SelectParticles()

SelectParticles::SelectParticles	(	const WarpXParticleContainer &	pc,
		WarpXParIter &	a_pti,
		amrex::Real	current_z_boost,
		amrex::Real	old_z_boost,
		int	a_offset = 0 )

Constructor of SelectParticles functor.

Parameters

[in]	pc	WarpX particle container
[in]	a_pti	WarpX particle iterator
[in]	current_z_boost	current z-position of the slice in boosted frame
[in]	old_z_boost	previous z-position of the slice in boosted frame
[in]	a_offset	index offset for particles to be selected

Member Function Documentation

◆ operator()()

template<typename SrcData>

AMREX_GPU_HOST_DEVICE int SelectParticles::operator()	(	const SrcData &	src,
		int	i ) const

inlinenoexcept

Functor call. This method determines if a given particle should be selected for Lorentz transformation in obtaining the lab-frame data. The particles that with positions that correspond to the specific z-slice in boosted frame are selected.

Template Parameters

SrcData type of source data

Parameters

[in]	src	SrcData particle tile data
[in]	i	particle index

Returns: 1 if particles is selected for transformation, else 0
