Components

TypeVisibility AttributesNameInitial
integer(kind=ip), public :: nradii

The number of radii the observer should observe at.
integer(kind=ip), public :: ioo_id

The file unit number this observer should use for output.
character(len=:), public, allocatable:: vname

The name of the observer.
real(kind=wp), public, dimension(:), allocatable:: radii

A 1d-array containing the radii that the observer should observe at. On allocation the size is nradii.
integer(kind=ip), public, dimension(:), allocatable:: elem_index

A 1d-array containing the index of all the elements that contains radii.
integer(kind=ip), public, dimension(:), allocatable:: node_index

A 1d-array containing the node index within all the elements that contains radii.
type(scal_schw), public, pointer:: p

A pointer to the scal_schw equation that provides the data.
real(kind=wp), public, dimension(:), allocatable:: fl

The -modes of the regular field at the particle location.
real(kind=wp), public, dimension(:), allocatable:: ftl

The -modes of the time derivative of the regular field at the particle location.
real(kind=wp), public, dimension(:), allocatable:: fphil

The -modes of the derivative of the regular field at the particle location.
real(kind=wp), public, dimension(:), allocatable:: frl

The -modes of the radial derivative of the regular field at the particle location.

Finalization Procedures

final :: close_sf_observer

The finalizer.


Type-Bound Procedures

procedure, public :: init => sf_init

The init routine is provided by sf_init

  • interface

    public module subroutine sf_init(this, rad, coord, object)

    The interface for the sf_observer version of init. This interface is consistent with obs_init_interface.

    Arguments

    Type IntentOptional AttributesName
    class(sf_observer), intent(inout) :: this

    The self-force observer that is being initialized.
    real(kind=wp), intent(in), dimension(:):: rad

    A 1d-array containing the radii where the observations have to be performed. Obviously it only makes sense to pass in the particle location.
    type(rgf), intent(in) :: coord

    A real grid function containing the coordinates of the grid.
    class(*), intent(in), target:: object

    The object on which observations have to be done. This has to be of type scal_schw.

procedure, public :: extract => sf_extract

The extract routine is provided by sf_extract

procedure, public :: output => sf_output

The output routine is provided by sf_output
