Detailed Description

Projects the regular field \(\Psi^R\) and its time derivative \(\partial_t \Psi^R\) onto real spherical harmonics and sends the result to the worldtube.

Details

The regular field is obtained by subtracting the singular/puncture field from the numerical DG field. All spherical harmonics are computed for \(l <= n\), where \(n\) is the worldtube expansion order. The projection is done by integrating over the DG grid of the element face using definite_integral with the euclidean area element. The worldtube adds up all integrals from the different elements to obtain the integral over the entire sphere.
