Roadmap: AMR for parabolic terms on `TreeMesh` and `P4estMesh`

2

From today's meeting: - [x] we'll first merge [this PR on AMR for parabolic terms on `TreeMesh`](https://github.com/trixi-framework/Trixi.jl/pull/1629) - [x] next, we'll work on merging the [PR for AMR with parabolic...

Is Trixi.jl suitable for simulation of acoustic wave through inhomogeneous media ?

4

Sorry for this probably dumb question, but I wonder if Trixi.jl is suitable for simulation of acoustic wave through (3D) inhomogeneous media (in time domain) ? I have seen the...

Move elixirs that are only relevant for testing to `test` directory

I already suggested this back in #569 when we organized the elixirs in folders based on mesh type, but I would like to give it another thought. There are some...

We test a couple of fluxes for rotational invariance https://github.com/trixi-framework/Trixi.jl/blob/1b75f5ecbd0b21d5cdce25f3e4f1884a06727fbb/test/test_unit.jl#L1174-L1195 and consistency: https://github.com/trixi-framework/Trixi.jl/blob/1b75f5ecbd0b21d5cdce25f3e4f1884a06727fbb/test/test_unit.jl#L614-L624 (for instance) This could be expanded for other fluxes.
