We are organising a two-day international scientific workshop at the Stellar Astrophysics Centre, Aarhus, Denmark, with the motivation for bringing together the community of core developers and users of the Stagger code.

Stagger is a first-rate numerical code designed for radiation-magnetohydrodynamics and computational astrophysical-flow simulations on high-performance computing (HPC) systems.
