Detailed Description

Computes the final acceleration of the particle at this time step.

Details

If max_iterations is 0, the acceleration will simply be geodesic, see gr::geodesic_acceleration. Otherwise, the acceleration due to the scalar self-force is additionally applied to it, see self_force_acceleration. This mutator is run on the worldtube singleton chare.
