You could use the [Visualization Callback](https://trixi-framework.github.io/Trixi.jl/stable/reference-trixi/#Trixi.SaveSolutionCallback) to write out files at a specified interval. They can be converted to VTK using [Trixi2Vtk](https://trixi-framework.github.io/Trixi.jl/stable/visualization/#Trixi2Vtk) and you could then use e.g. Paraview to...

So far we cannot reproduce the error you got. And the photo did not go through. I just did the following: - cloned TrixiShallowWater.jl - created a subdirectory `run` -...

Don't worry about the console output (https://github.com/trixi-framework/Trixi.jl/issues/2349). Your simulation was successful and you should be able to run trixi2vtk next.

Compressible Navier-Stokes equations is definitely our business. Maybe also in a pipe if you could start with a 2D setup or have a 3D mesh in a format which Trixi...

> Do you think the MPI failures are really unrelated? No, I am not sure. I just know that we had stalling CI jobs before. And, looking trough the recent...

t8code 3.0.0 has been released and @jmark already updated t8code_jll.jl. Does T8code.jl need an update as well?

Concerning the failing invalidations check, see https://github.com/timholy/SnoopCompile.jl/issues/397

Looking at https://github.com/trixi-framework/Trixi.jl/blob/main/src/meshes/t8code_mesh.jl#L316-L323, it seems to me the following assumptions are being made: 1. A 2D mesh lies in the x-y-plane in 3D space, i.e. z is always 0. 2....

@sandro-elsweijer's mesh lies in the x-y plane. ✔️ But the normals in the screenshot point in *negative* z-direction. In case the computation of the normals in paraview works similar to...

Yes, that makes sense! Cf. https://trixi-framework.github.io/TrixiDocumentation/stable/meshes/unstructured_quad_mesh/ The problem would then be like ``` 4---3 2---3 | | vs | | 1---2 1---4 ```
