Dispatching of `analyze` for parabolic terms

1

Currently, in `analysis.jl` there are two versions of the `analyze` function. The original one (for the hyperbolic solver) dispatches only on `semi::AbstractSemidiscretization`. A new (experimental) version of `analyze` for the...

P4est MPI simulation gets stuck when not all ranks have BC faces

4

I first encountered this issue for the baroclinic instability test case. Then I found a reduced example based on elixir_advection_basic but with nonperiodic boundary conditions: - 3 cells - 3...

Make custom integrators more similar to OrdinaryDiffEq.jl integrators?

5

While looking at the [`elixir_euleracoustics_co-rotating_vortex_pair.jl`](https://github.com/trixi-framework/Trixi.jl/blob/main/examples/tree_2d_dgsem/elixir_euleracoustics_co-rotating_vortex_pair.jl) I noticed that this can only be run with the integrators from `OrdinaryDiffEq.jl` because the `EulerAcousticsCouplingCallback` requires a `step!` function https://github.com/trixi-framework/Trixi.jl/blob/18aaae96035a995e840e4e262964e7b49fdd9325/src/callbacks_step/euler_acoustics_coupling.jl#L189 and an `init` function...

Raise your hands if you haven't encountered this situation at least once before: You tinker with a new feature implementation and/or simulation setup. Finally, you get it to run. For...
