Implement exact Riemann solver as hydro option #2285

Open maxpkatz opened 1 year ago

maxpkatz commented 1 year ago

It would be interesting to have an option to run the exact Riemann solver in the main Castro code, so we could more easily compare both accuracy and performance for any particular problem setup between the approximate/HLL solvers and the exact solver.

this will be straightforward once #2869 is merged. Then there is just a bit more cleaning.

once #2897 is merged, I can move the relevent headers into Castro/Source/hydro and then hook this in as an option.
