Even though in principle Poisson gravity can be used in the places where we currently use monopole gravity, we use monopole gravity only in 1D spherical coordinates (and can use...

In trace_ppm.cpp, the geometric source terms are added to the states with a mysterious `eta` factor that depends on the Courant number. We should instead include the geometric source terms...

Sometimes we use eos_input_re instead of eos_input_rt, but it is not clear if that is always needed. If the temperature has already be set, then can be used. For example,...

`update_sources_after_reflux` re-evaluates all source terms after a reflux on all levels. The logic is that the distribution of matter on the grid has changed, so the new-time source terms we...
