Functions/Subroutines
subroutine, public	dielectric_initialize (tree, cfg)
subroutine, public	dielectric_update_surface_charge (box, surface, dt, n_prev, s_prev, w_prev, s_out)
	Update charge on dielectric surface based on particle fluxes. In case of secondary emission, also update the electron density next to the surface.
subroutine, public	dielectric_photon_emission (box, surface, dt, s_out)
subroutine, public	dielectric_photon_absorption (tree, xyz_start, xyz_end, n_dim, n_photons, photon_weight)
	Determine whether and where photons hit a dielectric, and change their absorption location to the first cell inside the surface. If photons_no_absorption is true, assume that photons are not absorbed by the gas (so extrapolate their path).

Detailed Description

Module with settings and routines to handle dielectrics.

Todo:

Make sure species densities are initially zero inside the dielectric

Use special prolongation for multigrid when there are surface charges

dielectric_initialize()

subroutine, public m_dielectric::dielectric_initialize	(	type(af_t), intent(in)	tree,
		type(cfg_t), intent(inout)	cfg
	)

Definition at line 56 of file m_dielectric.f90.

dielectric_photon_absorption()

subroutine, public m_dielectric::dielectric_photon_absorption	(	type(af_t), intent(in)	tree,
		real(dp), dimension(3, n_photons), intent(in)	xyz_start,
		real(dp), dimension(3, n_photons), intent(inout)	xyz_end,
		integer, intent(in)	n_dim,
		integer, intent(in)	n_photons,
		real(dp), intent(in)	photon_weight
	)

Determine whether and where photons hit a dielectric, and change their absorption location to the first cell inside the surface. If photons_no_absorption is true, assume that photons are not absorbed by the gas (so extrapolate their path).

dielectric_photon_emission()

subroutine, public m_dielectric::dielectric_photon_emission	(	type(box_t), intent(inout)	box,
		type(surface_t), intent(inout)	surface,
		real(dp), intent(in)	dt,
		integer, intent(in)	s_out
	)

Parameters

[in]	dt	Time step
[in]	s_out	Output state

subroutine, public m_dielectric::dielectric_reset_photons

Definition at line 358 of file m_dielectric.f90.

dielectric_update_surface_charge()

subroutine, public m_dielectric::dielectric_update_surface_charge	(	type(box_t), intent(inout)	box,
		type(surface_t), intent(inout)	surface,
		real(dp), intent(in)	dt,
		integer, intent(in)	n_prev,
		integer, dimension(n_prev), intent(in)	s_prev,
		real(dp), dimension(n_prev), intent(in)	w_prev,
		integer, intent(in)	s_out
	)

Update charge on dielectric surface based on particle fluxes. In case of secondary emission, also update the electron density next to the surface.

Parameters

[in]	n_prev	Number of previous states
[in]	s_prev	Previous states
[in]	w_prev	Weights of previous states
[in]	s_out	Output state
