struct intrp::callbacks::ObserveSurfaceData< TagsToObserve, InterpolationTargetTag, HorizonFrame >

post_interpolation_callback that outputs 2D "volume" data on a surface and the surface's spherical harmonic data

Details

Uses:

• Metavariables
  • temporal_id
• DataBox:
  • TagsToObserve (each tag must be a Scalar<DataVector>)

Conforms to the intrp::protocols::PostInterpolationCallback protocol

For requirements on InterpolationTargetTag, see intrp::protocols::InterpolationTargetTag

The columns of spherical harmonic data written take the form

[Time, {Frame}ExpansionCenter_x, {Frame}ExpansionCenter_y,
{Frame}ExpansionCenter_z, Lmax, coef(0,0), ... coef(Lmax,Lmax)]

where coef(l,m) refers to the strahlkorper coefficients stored and defined by ylm::Strahlkorper::coefficients() const. It is assumed that $l_{max}=m_{max}$.

Note

Currently, $l_{max}$ for a given surface does not change over the course of the simulation, which means that the total number of columns of coefficients that we need to write is also constant. The current implementation of writing the coefficients at one time assumes $l_{max}$ of a surface remains constant. If and when in the future functionality for an adaptive $l_{max}$ is added, the implementation for writing the coefficients will need to be updated to account for this. One possible way to address this is to have a known maximum $l_{max}$ for a given surface and write all coefficients up to that maximum $l_{max}$.
