species_element_config_type

Components

Type	Visibility		Name		Initial
logical,	public	::	exist	=	.false.	Does the related namelist exist in the target input file?
integer,	public	::	index	=	0	Used to hold the specific index of numbered namelists
logical,	public	::	skip_read	=	.false.	Do we want to skip the read step in init?
logical,	public	::	skip_broadcast	=	.false.	Do we want to skip the broadcast step in init?
real,	public	::	bess_fac	=	1.0	Multiplies the argument of the Bessel function for this species. Useful for exploring the effect of the Bessel functions.
real,	public	::	dens	=	1.0	Set the normalised density for this species
real,	public	::	dens0	=	1.0	Parameter used for a few specific initial condition types. Todo Consider moving this parameter to init_g_knobs.
character(len=20),	public	::	f0type	=	"maxwellian"	Select which type of background distribution should be assumed for this species. Must be one of: 'maxwellian' : Standard maxwellian 'tabulated' : A general tabulated form 'sdanalytic' : A analytic slowing down form. See G. Wilkie thesis.
real,	public	::	fprim	=	2.2	Normalised inverse density gradient: $-\frac{1}{n}\frac{dn}{d \rho_N}$ (Note here $\rho_N$ is the normalised radius $\frac{\rho}{L_\textrm{ref}}$ .
real,	public	::	mass	=	1.0	Normalised mass of this species
real,	public	::	nu_h	=	0.0	Set the species hyper collision frequency used in the pitch angle scattering collision operator if [[collision_knobs::hypermult]] is `true`.
real,	public	::	temp	=	1.0	Set the normalised species temperature
real,	public	::	tpar0	=	0.	Parameter used for a few specific initial condition types. Todo Consider moving this parameter to init_g_knobs.
real,	public	::	tperp0	=	0.	Parameter used for a few specific initial condition types. Todo Consider moving this parameter to init_g_knobs.
real,	public	::	tprim	=	6.9	Normalised inverse temperature gradient: $-\frac{1}{T}\frac{dT}{d \rho_N}$ (Note here $\rho_N$ is the normalised radius $\frac{\rho}{L_\textrm{ref}}$ .
character(len=20),	public	::	type	=	"default"	Sets the characterisation of the species. Should be one of 'ion' : Thermal ion species 'default' : Same as 'ion' 'electron' : Thermal electron species 'e' : Same as 'electron' 'trace' : Tracer species 'hybrid_electron' : Adiabatic passing electrons, full trapped electron treatment. NOTE: This option is currently considered experimental and is intended for use in electrostatic simulations. This primarily controls the treatment in the collision operator, the detection of adiabatic species. Tracer species do not contribute to velocity space integrals.
real,	public	::	u0	=	1.0	Parameter used for a few specific initial condition types. Todo Consider moving this parameter to init_g_knobs.
real,	public	::	uprim	=	0.0	Controls an energy independent part of a source term. Note Documentation needs improving, looks like it's an early attempt at adding in the parallel flow shear drive term
real,	public	::	uprim2	=	0.0	Controls an energy dependent part of a source term. Note Documentation needs improving, looks like it's an early attempt at adding in the parallel flow shear drive term
real,	public	::	vcprim	=	-999.9	Part of the `sdanalytic` slowing down model. See G. Wilkie thesis.
real,	public	::	vcrit	=	-1.0	Part of the `sdanalytic` slowing down model. See G. Wilkie thesis.
real,	public	::	vnewk	=	0.0	Sets the normalised species-species collisionality frequency. For species s, `vnewk = nu_ss Lref/vref` where Lref is the reference length, `vref` is the reference thermal speed (not the thermal speed of species s!), $\nu_{ss}=\sqrt{2}\pi n_s Z_s^4 e^4 \log(\lambda)/\sqrt{m_s}T^{3/2}_s$ is a dimensional collision frequency, e is the proton charge, $\log(\lambda)$ is the Coloumb logarithm, and $Z_s,T_s,n_s,m_s$ are the (charge, temperature, density, mass) of species s. (The dimensional collision frequency given here is in Gaussian units. For SI units, include an extra factor $(4\pi\epsilon_0)^2$ in the denominator of the definition of $\nu_{ss}$ .
real,	public	::	z	=	1.0	Normalised species charge
