Function Documentation

hard_edged_fraction()

AMREX_GPU_HOST_DEVICE AMREX_FORCE_INLINE amrex::ParticleReal hard_edged_fraction	(	const amrex::ParticleReal	z,
		const amrex::ParticleReal	zpvdt,
		const amrex::ParticleReal	zs,
		const amrex::ParticleReal	ze )

Calculate the residence correction, the fraction of the time step the particle spends inside of the hard edge lattice element.

Parameters

[in]	z	the current location of the particle
[in]	zpvdt	the estimated future location of the particle, z + v*dt
[in]	zs	the start of the lattice element
[in]	ze	the end of the lattice element

Returns

the fraction is returned
