Classes  
struct  CheckInputFile 
Dummy tag that throws an error if the input file does not describe a circular orbit. More...  
struct  ElementFacesGridCoordinates 
A map that holds the grid coordinates centered on the worldtube of all element faces abutting the worldtube with the corresponding ElementIds. More...  
struct  ExcisionSphere 
The excision sphere corresponding to the worldtube. More...  
struct  ExpansionOrder 
The internal expansion order of the worldtube solution. More...  
struct  FaceCoordinates 
An optional that holds the coordinates of an element face abutting the worldtube excision sphere. If the element does not abut the worldtube, this holds std::nullopt. This tag should be in the databox of element chares. The available frames are Grid and Inertial. The Centered template tag can be turned on to center the coordinates around the position of the scalar charge. More...  
struct  FaceCoordinatesCompute 
struct  InertialParticlePosition 
The position of the scalar charge particle orbiting a central black hole given in inertial coordinates. We currently assume a circular orbit in the xyplane with radius \(R\) and angular velocity \(\omega = R^{3/2}\), where grid and inertial coordinates are equal at t = 0. More...  
struct  InertialParticlePositionCompute 
struct  Psi0 
Holds the constant coefficient of the regular field inside the worldtube. More...  
struct  PsiMonopole 
Holds the monopole of the regular field inside the worldtube. More...  
struct  PunctureField 
struct  PunctureFieldCompute 
struct  RegularFieldInbox 
Inbox of the element chares that contains the regular field \(\Psi^R\) as well as its time and spatial derivative evaluated at the grid points of abutting element faces. More...  
struct  SphericalHarmonicsInbox 
Inbox of the worldtube singleton chare which receives quantities projected onto spherical harmonics. More...  
struct  WorldtubeSolution 
The solution inside the worldtube, evaluated at the face coordinates of an abutting element. This tag is used to provide boundary conditions to the element in CurvedScalarWave::BoundaryConditions::Worldtube . More...
