run_parameters Module

Does the related namelist exist in the target input file?

Used to hold the specific index of numbered namelists

Do we want to skip the read step in init?

Do we want to skip the broadcast step in init?

The maximum wall clock time available to GS2

$\beta$ is the ratio of the reference pressure to the reference magnetic energy density, $\beta=2\mu_0n_{ref}T_{ref}/B^2_{ref}$.

Initial timestep

Determines how initial timestep is set. Possible options are:

If true then use eigensolver instead of initial value solver.

Advanced option to freeze evolution of certain modes. Possible values are:

Multiplies $A_\|$ throughout.

Multiplies $B_\|$ throughout.

Multiplies $\phi$ throughout.

Determines the behaviour when the CFL condition is broken in the nonlinear term:

Used in ginit_option "harris" and "convect". Should be moved to init_g namelist.

How close to avail_cpu_time can we go before trying to stop the run cleanly

The simulation time after which the run should stop.

Sets the time step interval at which check for the existence of the .stop file.

Maximum number of steps to take

How frequently, in integer steps, do we display a progress message. If <= 0 then no progress messages are displayed

Normalised gyro-radius, only used for low flow builds

If true then save init timer information to .init_times.

If true then save some extra timer information to .timing_stats giving min/max/mean values.

Used to set the random seed used in the random number generators provided by ran. If this input is 0 (the default) then we don't set the seed and use the system default instead.

Only used when there is an adiabatic species. Sets n q ^2 / T of the adiabatic species, normalised to the reference values.

If true use original diagnostics rather than new form

Custom description of run to be added to netcdf output (new diagnostics only)

If true makes timestep proportional to ky*rho. Only sensible for linear runs.
