Often, we need some estimates of the wave speeds, e.g.
- for CFL-based time step control
- for numerical fluxes like local Lax-Friedrichs, Harten-Lax-van Leer
In principle, multiple estimate …

It's not clear to me if the issue seems to be with the package EinsteinPy or with SymPy itself.
I am unable to evaluate the Ricci and Einstein tensors for a specific metric. The same error occurs i…

I'm doing my own implementation of the GERG2008 equation in Fortran90, focused on making it a Python module later.
Using the binary test data available in this repo I've noticed that my implementatio…

Hello.
Could someone please comment on the ease of using Trixi for the simulation of a multidimensional Fokker-Planck equation (for particle distributions)? In essence, I want to simulate an advectio…

Hi,
Would it be possible to ask the user the functions a,b,c and for a robin BC and it will provide an `equation` to solve:
`∇(a(x,u)∇u) + ∇(b(x,u)u) + c(x,u) u = 0`

This is basically taken from #1136. Currently, our idea is to merge the `DGMulti` setup from that PR into `dev`, draft a corresponding `TreeMesh` & `DGSEM` version in another PR, and see how it looks …
