Detailed Description

Builds and advances the externally imposed antenna potential.

The antenna converts the configured radial envelope and poloidal/toroidal mode spectrum into a B-spline field compatible with FieldsModule. It solves the selected quasineutrality/mass-matrix problem at two temporal phases and combines those cached fields during the timestep. This is the C++ analogue of antenna_mod in antenna.F90 and consumes the process-wide AntennaVariables populated by ReadInput.

Note

ORB5X coordinates and time are normalized: \(s\) is the normalized flux-surface radius, angles are radians, and time is in \(\Omega_i^{-1}\).

Member Function Documentation

add_antenna_source()

static void orb5x::AntennaModule::add_antenna_source ( int  step )

static

Advance the antenna field for a global timestep.

Parameters

[in]

step

Zero-based global timestep; converted to time with basic->dt.

destroyStaticViews()

static void orb5x::AntennaModule::destroyStaticViews ( )

static

Release static Kokkos allocations before Kokkos::finalize().

get_antenna_source()

static Real orb5x::AntennaModule::get_antenna_source ( Real  s, Real  chi, Real  phi, Real  time  )

static

Evaluate the configured analytic antenna source at one point.

Parameters

[in]	s	Normalized radial coordinate.
[in]	chi	Poloidal angle [rad].
[in]	phi	Toroidal angle [rad].
[in]	time	Normalized time \(t\Omega_i\).

Returns

Radial-envelope times mode-spectrum times temporal coefficient, in the normalized potential/source units of the configured amplitudes; zero when the antenna is disabled.

init_antenna()

static void orb5x::AntennaModule::init_antenna ( FieldsModule *  fields_module = nullptr )

static

Initialize antenna metadata, storage, and the configured radial profile.

Parameters

[in]

fields_module

Field subsystem used to allocate phi_antenna; may be null only for the disabled/incomplete initialization path.

init_field()

static void orb5x::AntennaModule::init_field ( )

static

Assemble and solve the antenna field at the required temporal phases.

Populates phi_antenna and, for nonzero frequency, field_t0_bspl and field_tquarter_bspl. The selected antenna type chooses the quasineutrality or mass matrix, following init_field in antenna.F90.

load_antenna_config()

static void orb5x::AntennaModule::load_antenna_config ( const std::string &  fname )

static

Load scalar antenna settings from a simple key = value file.

Parameters

[in]

fname

Input file path. Missing files terminate the run.

Note

Mode arrays remain owned by AntennaVariables and are not parsed here.

update_field()

static void orb5x::AntennaModule::update_field ( Real  time )

static

Reconstruct the instantaneous antenna potential from cached phases.

Parameters

[in]

time

Normalized simulation time \(t\Omega_i\).

Member Data Documentation

phi_antenna

FieldType orb5x::AntennaModule::phi_antenna

static

Antenna electrostatic potential and its B-spline/grid representations.
