Outputs

Output quantities are normalised, with the normalisation factors stored in the output files

Table 1 Normalisation quantities

Name	Description	Units
Nnorm	Density	m\(^{-3}\)
Tnorm	Temperature	eV
Cs0	Speed	m/s
Omega_ci	Time	1/s
rho_s0	Length	m

The following variables are stored in the output file if they are evolved:

Name	Description	Normalisation
Ne	Plasma density	Nnorm [\(m^{-3}\)]
NVi	Plasma flux	Nnorm\(\times\)Cs0 [\(m^{-2}s^{-1}\)]
P	Plasma pressure	e\(\times\) Nnorm\(\times\)Tnorm
Nn	Neutral density	Nnorm [\(m^{-3}\)]
NVn	Neutral flux	Nnorm\(\times\)Cs0 [\(m^{-2}s^{-1}\)]
Pn	Neutral pressure	e\(\times\) Nnorm\(\times\)Tnorm

The following rates and coefficients are also stored:

Note that the R term is energy which is lost from the system, whilst E is energy which is transferred between plasma and neutrals. For all transfer terms (S, F, R) a positive value means a transfer from plasma to neutrals.

To diagnose atomic processes, turn on diagnose = true in the input settings (this is the default). Additional outputs contain the contributions from each atomic process. They have the same normalisation factors as the corresponding (S, F, R) term.
