Components

Type Visibility Attributes 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 :: akx_max = 0.0

Max kx for periodic finite kx ballooning space runs with .
real, public :: akx_min = 0.0

Min kx for periodic finite kx ballooning space runs with .
real, public :: aky_max = 0.0

Upper limit of range. Should set to something other than zero.
real, public :: aky_min = 0.0

Lower limit of range. Should typically set to something other than zero.
character(len=20), public :: kyspacing_option = 'default'

Sets the type of spacing between ky grid points, available options are :

  • 'default' : Same as 'linear'
  • 'exponential' : Evenly spaced in log(ky).
  • 'linear' : Evenly spaced in ky.
integer, public :: n0_max = 0

Maximum toroidal mode number. Can use instead of aky_max.
integer, public :: n0_min = 0

Minimum toroidal mode number. Can use instead of aky_min.
integer, public :: naky = 1

The number of 'actual' ky modes.
integer, public :: nn0 = 1

Number of toroidal modes, only used if n0_min>0. Overrides naky in kt_grids_range_parameters. Note if the number of modes isn't compatible with the requested min and max toroidal mode numbers then we just run with one mode, determined by n0_max.
integer, public :: ntheta0 = 1

Number of (kx) modes
real, public :: rhostar_range = 1.0e-4

Used to convert n0_min, n0_max range into aky_min, aky_max, if n0_min>0. If n0_min is set, aky_min=n0_min*drhodpsi*rhostar_range and aky_max=n0_max*drhodpsi*rhostar_range where drhodpsi is calculated as a part of the geometry setup.
real, public :: theta0_max = 0.0

Upper limit of theta_0 range
real, public :: theta0_min = 0.0

Lower limit of theta_0 range
