Variables

TypeVisibility AttributesNameInitial
real(kind=wp), public :: rho_min

The minimal coordinate point on the grid. With hyperboloidal coordinates this is the location of the horizon. Gets initialized to the value of the parameter Sminus.
real(kind=wp), public :: rho_max

The maximal coordinate point on the grid. With hyperboloidal coordinates this is the location of scri+. Gets initialized so that the particle location is the center of the grid.
real(kind=wp), public :: rho_particle

The coordinate location of the center of the grid. When a particle is used it gets initialized to the tortoise coordinate location of the midpoint of the orbit. When a particle is not used it gets initialized to the value of the parameter r_center converted to tortoise coordinates.
real(kind=wp), public :: Tminus

The tortoise coordinate location of the inner boundary of the region where time dependent coordinates are used.
real(kind=wp), public :: Tplus

The tortoise coordinate location of the outer boundary of the region where time dependent coordinates are used.
real(kind=wp), public :: delta_rho_min

The smalles coordinate distance between any two DG nodes on the grid.
type(rgf), public :: rho

A real grid function containing the computational coordinate, .
type(rgf), public :: drhodr

A real grid function containing where is the node coordinates in the reference element ().
type(rgf), public :: drdrho

A real grid function containing .
integer(kind=ip), public, dimension(2):: Tminus_ind

A size 2 integer array containing the element indices of the two elements that border the lower boundery of the time dependent coordinate region.
integer(kind=ip), public, dimension(2):: Tplus_ind

A size 2 integer array containing the element indices of the two elements that border the upper boundery of the time dependent coordinate region.
integer(kind=ip), public, dimension(2):: particle_element

A size 2 integer array containing the element indices of the two elements that has the particle on their boundary.
integer(kind=ip), public, dimension(2):: particle_node

A size 2 integer array contining the node indeces of the particle location in the two elements that contain the particle.
