Detailed Description

template<typename System, ::dg::Formulation DgFormulation>
struct evolution::dg::ConservativeDuDt< System, DgFormulation >

Calculate \(\partial u/\partial t\) for a conservative system.

The time evolution of the variables \(u\) of any conservative system is given by \(\partial_t u = - \partial_i F^i + S\), where \(F^i\) are the fluxes and \(S\) are the sources.

Source terms are only added for variables in the System::sourced_variables type list.
