Detailed Description

Compute the RHS terms of the evolution equations for the scalar tensor system.

Details

The bulk of the computations in this class dispatch to GeneralizedHarmonic::TimeDerivative and CurvedScalarWave::TimeDerivative as a 'product system' – each independently operating on its own subset of the supplied variable collections. The additional steps taken are to compute the trace-reversed stress energy tensor associated with the scalar part of the system and add its contribution to the \(\partial_t \Pi_{a b}\) variable in the Generalized Harmonic system, as well as adding any scalar sources to the variable \(\partial_t \Pi\).

Warning

Backreaction of the scalar field onto the metric is currently disabled and the system is evolved in the test-field (or decoupling) approximation.
