semi-structured AMG for radiation solve

1

There is a new "semi-structured" AMG solver (SSAMG) in Hypre: https://arxiv.org/abs/2205.14273. They claim it significantly reduces the setup time compared to the existing AMG solver, since it assumes logically-Cartesian mesh...

implement inflow BCs for the flame

1

## PR summary This will allow us to inflow fuel in through the right boundary to hold the flame roughly stationary. Better still, it will hopefully remove the influence of...

[WIP] add renomalization after the update

1

## PR summary in some sense, this mirrors what we would do with Strang or simplified-SDC, since we always renormalize after leaving the burner. ## PR motivation ## PR checklist...

Using this issue to keep track of what's necessary. My initial thought is that we don't really need to backup any part of the advance. If we run into an...

For the radiation diffusion or moment equations, after discretizing in time, one can eliminating all variables in the radiation equations except the radiation energy density. After obtaining the radiation energy...

We should call `ppm_reconstruct_pslope` in `Castro_mol.cpp`

for retry after burning fail, we can use the time from burn_t

2

When we run with `use_retry` and we encounter a burn failure, we can estimate the number of retries needed simply by looking at `dt / burn_t burn_state.time`. This might be...

have reaction loop print out failures even when on GPU

3

Currently, when running on the GPU, the different integrators do not print out the failures. But we now have standardized error codes, which we can add to the `burn_t`. Then...
