Source Code


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 :: gamma0 = 0.0

Growth rate of non-standard source used with source_option = 'phiext_full'.

real, public :: omega0 = 0.0

Frequency of non-standard source used with source_option = 'phiext_full'.

real, public :: phi_ext = 0.0

Amplitude of external phi added as source term with source_option = 'phiext_full'. If zero (default) then no extra term included in the source.

real, public :: source0 = 1.0

Amplitude of non-standard source used with source_option = 'phiext_full' when time >= t0.

character(len=20), public :: source_option = 'default'

Controls the source term used in the time advance. Should be one of:

  • 'source_option_full' : Solve GK equation in standard form (with no artificial sources)
  • 'default' : Same as 'source_option_full'
  • 'phiext_full' : Solve GK equation with additional source proportional to phi_ext*F_0.
  • 'homogeneous' : Solve the homogeneous equation, i.e. no potential related sources.
real, public :: t0 = 100.0

Turn on any artificial sources after time = t0. Only used with source_option = 'phiext_full'.
