We already print out which limiter is controlling the timestep, so this is half done already :-)

That is true. I'll note that since we already perform two AllReduce calls to get both the hydro and reactions limited timesteps, and doing one for diffusion would add a...

Seems like MPI_MINLOC (https://www.mpi-forum.org/docs/mpi-1.1/mpi-11-html/node79.html) could be useful for the location information.

The SCF implementation we do have already can account for a rotating reference frame and can generate non-spherical stars, although I don't have much practice with it yet. I don't...

@dmarce1 I figured I'd try something out to get the conversation started. If you take a look at the [scf_tests/single_star](https://github.com/AMReX-Astro/Castro/tree/main/Exec/scf_tests/single_star) problem setup, you'll find a setup that invokes the Hachisu...

It doesn't look like our SCF initial model is doing a good job yet establishing a polytropic star that's actually in equilibrium. Here is the case I mentioned above without...

OK, for now I'm going to stay away from gamma = 4/3 polytropes and their fun physical properties (I knew they were unstable to gravitational collapse but I didn't know...

The first plot was non-rotating n = 3, gamma = 4/3 polytrope. I think this is a thermodynamically consistent EOS but doesn't seem to result in a stable star. The...

@dmarce1 Sorry for the delay, I was on vacation for a little while. I hit a bit of a roadblock because I still don't feel that our SCF implementation (even...

As a comparison point for testing how this affects performance for an apples-to-apples test, build `Exec/science/wdmerger` with `make USE_CUDA=TRUE USE_MPI=TRUE DIM=3 TINY_PROFILE=TRUE`. This is the test case I ran on...
