Hey guys,
I've been doing some work on an implementation of MMS for use with codes based on integral methods (finite-volume, etc.), including situations that lead to shocks. I thought it might be a p…

Aim of this issue is to fix some misinterpretations of shock capturing parameters needed in SPH, namely choices of linear and non-linear shock parameters (alpha_AV and beta_AV).
Following several c…

We should check whether everything works using
- `Float32`
- `Float64` (current default)
- Types from [MultiFloats.jl](https://github.com/dzhang314/MultiFloats.jl) or [Quadmath.jl](https://github…

The goal is to bring over new technology from Fluxo, based on the shock capturing to implement automatic positivity preservation.

In additional to stabilizing advection with something like SUPG, we may want to stabilize interior layers (primarily the phase interface) with some kind of shock capturing method.

I use hifiles to compute a Ma=2.8 flow, I found it is very unstable when strong shock occurs. I read the code, found that the artificial viscosity is not added in 3D case(in function shock_capture_con…

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
- [x] Unstruct…

By _method_ I mean method for spatial discretization and ODE solving. Currently I'm just mimicking the settings in examples folder of Trixi somewhat blindly. Does there exist any rule of thumb for met…

Currently all limiter-related code lives in `src/Evolution/DiscontinuousGalerkin/SlopeLimiters`, and in namespace `SlopeLimiters`.
Now that we are implementing more types of limiters, including som…

The way 2D cases are handled is very confusing I think. These three attributes:
