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?
logical, public :: skip_smart_defaults = .false.

Do we want to skip the smaart defaults in init?
real, public :: amplitude = 0.0

Amplitude of Langevin antenna.
logical, public :: ant_off = .false.

Overrides all other options and turns off antenna if true.
integer, public :: nk_stir = 0

Number of independent Fourier modes driven by antenna.
logical, public :: restarting = .false.

If true then try to get initial antenna amplitudes from the restart file. If not found in restart file then will be set to 0.
real, public :: t0 = -1.0

Sets the time at which the antenna frequency changes from constant w_antenna to linearly varying, with linear piece proprtional to w_dot multiplied by time - t0.
complex, public :: w_antenna = (1.0, 0.0)

Frequency of Langevin antenna. Sets the constant part of the complex antenna frequency.
real, public :: w_dot = 0.0

Sets the coefficient in front of the time varying antenna frequency (real) component activated when time > t0.
logical, public :: write_antenna = .false.

Write antenna amplitudes to ASCII file for debugging.
