This is an unfinished list of ideas for Trixi tutorials that might be interesting to have: * A tutorial on how to use the [`AnalysisCallback`](https://trixi-framework.github.io/Trixi.jl/stable/reference-trixi/#Trixi.AnalysisCallback) to extract analysis quantities over...

Currently, our MPI-aware mesh constructors are not type-stable since they check for a runtime value (whether we run with MPI) to determine the type of the mesh (serial or MPI-parallel)....

Passing in explicit arguments instead of `cache`

4

There are some functions with signature `function_name!(cache, …)` where `cache` is passed in as an output argument. This makes the code more confusing, since modifying a field of cache makes...

Allow different numbers of variables in `PlotData2D`

With StructArrays.jl v0.6.8: ```julia julia> using Trixi, OrdinaryDiffEq, Plots julia> trixi_include("examples/structured_2d_dgsem/elixir_advection_extended.jl") julia> PlotData2D(sol) # fine PlotData2DTriangulated{Matrix{Float64}, StructArray{SVector{1, Float64}, 2, Tuple{Matrix{Float64}}, Int64}, Matrix{Float64}, StructArray{SVector{1, Float64}, 2, Tuple{Matrix{Float64}}, Int64}, SVector{1, String}}(, ,...

Discovered by @gregorgassner: We can, say, pass non-periodic `boundary_conditions` to the `SemidiscretizationHyperbolic` while the `TreeMesh` is still periodic by default. It would be nice to have some check whether that's...

Help understanding flux limiter implementation

3

Hi! I'm the lead developer over at [MethodOfLines.jl](https://github.com/SciML/MethodOfLines.jl), and it's come time for me to implement flux limiters for use when solving Hyperbolic PDEs. In trying to understand how to...

Adding 3D isosurface visualization

2

Currently, Trixi does not support plotting 3D isosurfaces. These changes will support this functionality. Currently, the way to create a 3D isosurface is to create a `pd = ScalarPlotData3D(some_scalar_array, semi)`...

Proof of concept: TrixiMPIArray

14

This is a rough draft of a possible MPI array type. A lot of TODO notes are left in the draft at the moment. Partially implemented in a reduced version...
