HPSC Lab at JuliaCon 2024

From July 9th through 13th, JuliaCon 2024 took place at the PSV soccer stadium in Eindhoven, Netherlands. It presented a great opportunity to meet a lot of fellow Julia users and developers and enabled many interesting face-to-face discussions with core Julia developers. It was also nice to meet a number of members of the Trixi Framework development team, such as Hendrik Ranocha (伟德国际_伟德国际1946$娱乐app游戏 of Mainz), Erik Faulhaber and Benedict Geihe (both 伟德国际_伟德国际1946$娱乐app游戏 of Cologne), and Daniel Doehring (RWTH Aachen 伟德国际_伟德国际1946$娱乐app游戏).

Niklas (HLRS Stuttgart/HPSC Lab) and Michael (HPSC Lab) were also present and gave talks on particle-based multiphysics simulations with TrixiParticles.jl?and on secure numerical computations with fully homomorphic encryption. Overall, it was a great event and we are looking forward to next year!

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.
