◆ particlesConvertUnits()

template<typename T_ParticleContainer>

void particlesConvertUnits	(	ConvertDirection	convert_direction,
		T_ParticleContainer *	pc,
		amrex::ParticleReal const	mass )

Convert particle momentum to/from SI

Particle momentum is defined as gamma*velocity, which is neither SI mass*gamma*velocity nor normalized gamma*velocity/c. This converts momentum to SI units (or vice-versa) to write SI data to file. Photons are a special case, since particle momentum is defined as (photon_energy/(m_e * c) ) * u, where u is the photon direction (a unit vector).

Template Parameters

T_ParticleContainer a WarpX particle container or AmrParticleContainer

Parameters

convert_direction	convert to or from SI
pc	the particle container to manipulate
mass	the particle rest mass to use for conversion

◆ storePhiOnParticles()

void storePhiOnParticles	(	PinnedMemoryParticleContainer &	tmp,
		ElectrostaticSolverAlgo	electrostatic_solver_id,
		bool	is_full_diagnostic )

Gathers phi (electrostatic potential) from a MultiFab to the macroparticles. Adds a runtime component of the particle container to store it.
