> What people instead do is hand-craft discretization methods that make use of special properties that their model has. These might or might not involve using AMR in the 3...

To do this we need to relax the requirement that unevolved species are ordered after evolved species and generalize the unevolved species update. We should also avoid evaluating rates that...

We can more easily automate tracking the map between species and rates with pynucastro, for other networks we will need to construct such maps.

Things seem more complicated when there are weak reactions and EOS Coulomb corrections ... In that equality, our "y" only tracks nuclear species. We also have electrons as another "species"...

This issue of double counting m_e if we use electron chemical potential may be what @jaharris87 was getting at by saying: "Changes in electron fraction should also be reflected in...

I've looked at the Mueller (1986) paper and it seems like that formulation does make this clearer and there is a path forward there by including electrons as a species...

In going through the SDC bits of the integrators in StarKiller Microphysics it is apparent they're set up for a different sort of SDC in Castro than Maestro has. The...
