The first TRUDI (Trixi User and Developer Interaction) workshop was organized by the University of Cologne during the 16th - 20th of March 2026. Our entire HPSC scientific team participated and presented their latest developments with Trixi.jl. We had various discussions with other Trixi.jl developers and users about the code, its future, Julia, performance, coupling, optimization and particle simulations. This event strengthened the team's collaboration efforts on an international level and future scientific efforts.
