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).

Variables

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

dielectric_reset_photons()

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