Units

There are three output files containing units parameters: xgc.units.bp in ADIOS2 format, units.m in MATLAB format and units.txt in plain text format.

xgc.units.bp
Printed when: always.   Output frequency: once at start/restart.

Description

ptl_charge_eu

Scalar

\(e\)

Input parameter ptl_charge_eu, i.e. ion charge number (charge in units of elementary charge \(e\)).

ptl_mass_au

Scalar

\(u\)

Input parameter ptl_mass_au, i.e. ion mass in atomic mass units (hydrogen mass \(m_{\mathrm{H}}~\approx~1u\)).

ptl_num

Positive integer

Units

This does not seem to be the same as the input parameter

sml_dt

Scalar

\(\mathrm{s}\)

Time step \(\Delta t\) in seconds. Note that the unit is different from the input parameter sml_dt which is given in units of toroidal transit time. Moreover, if a simulation is restarted with a different time step this output parameter will be updated to the last used step.
