Computation of viscous fluxes in the compressible Navier-Stokes equations computed using the gradients of the entropy variables. New functions are marked with "TODO: parabolic; entropy stable viscous terms". Currently, the...
This issue serves to collect what features / mesh types are available for the shallow water system: - [x] TreeMesh1D (see #1118) - [x] TreeMesh2D (see #890) - [x] StructuredMesh2D...
First prototype of a Grass model coupling for bedload transport in the shallow water system. Reuses a lot of the shallow water routines but now with a time dependent bottom...
A new type of AMR controller would be a good to have for unstructured meshes. Such a controller would incorporate the relative element size `h` measured in some way (e.g....
In the event when Trixi fails due to something like a negative density or pressure it would be helpful to add additional output that provides the `(x,y,z)` location where the...
In `solvers/dgsem_tree/dg_2d.jl` (and also in dg_1d.jl and dg_3d.jl) the `create_cache` and `!fv_kernel` have the capability of using all mesh types whereas the `VolumeIntegralPureLGLFiniteVolume` only has the TreeMesh type available. I...
The `split_form_kernel!` found in `solvers/dgsem_structured/dg_2d.jl` uses the matrix `derivative_split` from `dg.basis` which is zero along the main diagonal. In essence, this "peels off" the two volume contributions at the `[1,1]`...
The discussion in this section of `testing.md` should be updated in particular the coverage % value.
Further extensions of the functionality from #1855 are possible. Adding the ability of having gauge points on, e.g., a 1D `TreeMesh` should be straightforward. For instance, one does not need...
The operators described in the [arXiv paper](https://arxiv.org/pdf/2312.11452.pdf) are interesting because they modify the boundary closures to guarantee SBP and WENO. The downside is that the paper does not explicitly present...
