Unify signatures of mesh constructors

3

It may be nice to unify the signatures of some mesh constructors or provide additional convenience constructors. This can be nice when testing different meshes, e.g., for #1191. Right now,...

WIP: New shock capturing using subcell-wise blending

8

This PR adds the subcell shock capturing approach, as implemented in [fluxo](https://github.com/project-fluxo/fluxo). The volume integral `VolumeIntegralShockCapturingSubcell` uses the IDP indicator `IndicatorIDP` with 5 possible limiters (`IDPDensityTVD`, `IDPPressureTVD`, `IDPPositivity`, `IDPSpecEntropy`, `IDPMathEntropy`)....

Flux functions that depend explicitly on space

10

This came up in #356: It would be nice to allow flux functions that depend explicitly on space `x`, e.g. for linear advection with variable coefficients. There are at least...

Combined hyperbolic-parabolic equation type

9

This modifies `SemidiscretizationHyperbolicParabolic` to accept a "combined" type with `EquationsHyperbolicParabolic`, which is then passed into the initial condition. There main downside is that now if we wish to use an...

`p4est` bindings generated with Clang.jl

3

This is the Trixi.jl counterpart of https://github.com/trixi-framework/P4est.jl/pull/49 to find out what we need to do there to support everything we use in Trixi.jl. TODOs: - [ ] every comment `#...

Alternative and more direct way to interface to p4est/t8code

6

This issue is just FYI and open for discussion. Idea: Instead of relying on 3rd-party packages for generating interfaces to C libraries we write them "manually" by ourself and are...

Bring triangulation-plots on par with heatmap-plots

All of the following features already work for the heatmap approach: - [x] Interpolating in each element according to given "nndoes" - [x] Plotting the mesh - [x] Picking single...
