**Describe the bug**
We seem to be very susceptible to producing thin shells that are aligned with the grid axes when the thin-shell radius is not well resolved ($\Delta x \gg 10^{-2}$ pc).
**To R…

For compositional fields (and the temperature, for that matter), one can only impose Dirichlet conditions if we are at a point where there is *inflow*. We determine this here:

Document is needed so that Eli can work on implementing the test. There is
already a subroutine with this name but I don't think it is finished or

I am currently working on implementing the advection-diffusion equation in Trixi.jl. Upon reviewing the source code, I have observed that the semidiscretization for parabolic terms is handled within `…

There's a bug in `adapt_advection_order` (or the constructor for `HydrostaticFreeSurfaceModel`, since this code:
