Thanks for writing this all out. What would you think of doing [what Ratel does for multiple materials](https://gitlab.com/micromorph/ratel/-/blob/main/examples/ex02-quasistatic-elasticity-multi-material.yml). It would look like ```yaml bc: farfield,viscous_inflow,viscous_outflow,insulated_wall farfield: faces: 1,2 type: freestream...

Thanks @jrwrigh, it's there anything we should salvage in this branch or just close it as superseded?

I think I can fix it in a few minutes without much clutter.

Pushed. It builds cleanly for me with both `0.12` and `main`

Precise property testing isn't catching every time you accidentally turn an $O(n)$ algorithm into an $O(n^2)$ algorithm by calling `DMPlexGetSimplexOrBoxCells` in a loop. If PETSc had longitudinal performance testing, it...

That's a different sort of test harness. It would be a good project to create it, but it's going to be more intrusive than something we already know how to...

Until this issue is addressed, it would be nice for `hatch new --init` to warn/error if the original project uses extension modules. Would have saved me some time exploring why...

I just wanted to share this update from the const generics group lead: > In general though I would highly recommend migrating off of GCE and that nobody should be...

Hmm, I think `State{,Primitive,Conservative}` need not be "Newtonian" things (they have nothing to do with viscosity). Their conversions assume ideal gasses. So we could promote that concept to something that...

Sounds good to me. Newtonian is what matters for us (and at some point in the next few months, I think we'll add RANS).
