Function Documentation

BackScattering()

AMREX_GPU_HOST_DEVICE AMREX_INLINE void BackScattering	(	amrex::ParticleReal &	ux,
		amrex::ParticleReal &	uy,
		amrex::ParticleReal &	uz,
		const amrex::ParticleReal	uCOM_x,
		const amrex::ParticleReal	uCOM_y,
		const amrex::ParticleReal	uCOM_z
	)

Function to perform back scattering of a particle in the lab frame. The particle velocity is transformed to the COM frame where it is reversed. The resulting particle velocities are then transformed back to the lab frame and the input particle's velocity is updated.

Parameters

ChargeExchange()

AMREX_GPU_HOST_DEVICE AMREX_INLINE void ChargeExchange	(	amrex::ParticleReal &	ux,
