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 :: beta_div = 1.0

The minimum in scans is beta_prime_equilibrium/beta_div

real, public :: beta_mul = 1.0

The maximum in scans is beta_prime_equilibrium*beta_mul

real, public :: diff = 0.0

Controls decentring used in the numerical integration used for solving the ballooning equation. Recommended values are either 0 (default) or 1/3.

logical, public :: make_salpha = .false.

Not currently used for anything.

integer, public :: n_beta = 1

How many values should be used in s-alpha type scans.

integer, public :: n_shat = 1

How many values should be used in s-alpha type scans.

real, public :: shat_max = 0.0

The maximum value of to use in s-alpha type scans.

real, public :: shat_min = 0.0

The minimum value of to use in s-alpha type scans.

real, public :: theta0 = 0.0

The theta0 value to use in solving the ideal ballooning problem. We don't currently provide a means to study multiple theta0 in a single run. This may change in the future.
