Snapshot: Minisymposium on multiphysics coupling at the CSE25 in Fort Worth

Together with Yanick Kiechle from the Heinrich-Heine Universit?t Düsseldorf, we organized a minisymposium on numerical methods for coupled multiphysics problems at the CSE25 in Fort Worth, TX. We had a good range of topics, form coupling libraries to concrete applications in CFD. The speakers covered applications like supersonic flows, astrophysical plasmas and viscous fluids.

Using p4est meshes for our simulations we implemented flexible multiphysics coupling across interface boundaries in Trixi.jl. Unlike structured meshes, p4est meshes can be much more flexible. They do not require to be rectangular or even simply connected. As a test case we show here two meshes. One writes the word "Trixi.jl" and the other is its complement. We couple an MHD system with an Euler system and initialize the domain with a linear pressure wave that travels to the left.
