It would be nice to have a brief explanation of DG methods and their implementation in Trixi.jl in the docs. That part is different from https://github.com/trixi-framework/Trixi.jl/issues/169, since it should contain...

Timeout error for GitHub action CacheNotebooks

1

The GitHub action [repo2docker-action](https://github.com/jupyterhub/repo2docker-action) seems to have a maximum time allowed of 900s to trigger mybinder (implemented [here](https://github.com/jupyterhub/repo2docker-action/blob/86cbba650927d185d7cee256eb48d0a7eeb38906/trigger_binder.sh#L8)). So, our action fails with the timeout error `curl: (28) Operation timed...

Initial support for MPI parallelization

6

This issue is to keep track of the necessary steps towards an initial parallel octree implementation in Trixi. It should thus be amended as we progress and gather more experience...

Added 3D to 2D plotting along an axis/curve for general meshes

4

This PR introduces the possibility to create 2D-plots from 3D-solutions when using a general mesh. It works similar to the Tree-mesh version. Here are some examples: 1. elixir: "structured_3d_dgsem\elixir_advection_basic" (with...

How to handle default arguments of `solve`

2

We need some default arguments of `solve`, e.g., `save_everystep=false`. With our coming MPI array type, we also need to think about how to handle the parallel norm computations for error-based...

MPI performance on error calculations

1

Just a note to remind us of this setting https://github.com/trixi-framework/Trixi.jl/blob/141508f9d1a897e778f937490aa8764a123dc26c/src/callbacks_step/analysis_dg2d_parallel.jl#L15-L19 (since I couldn't find it in the other parallelization issues)

ranocha

Currently some initialization step after calling `solve` fails if one of the processes does not hold any elements. This issue came up in https://github.com/trixi-framework/Trixi.jl/pull/1091#issuecomment-1076440725.

Check influence of the step size controller on performance for SSPRK43 elixirs

6

The default `controller` with `SSPRK43()` in OrdinaryDiffEq.jl is a `PIController` with effective parameters `beta1 = 0.70, beta2 = -0.40`. However, this controller is not step size control stable. We should...
