Description
EUHFORIA (EUropean Heliospheric FORecasting Information Asset) is a widely used 3D magnetohydrodynamic (MHD) simulation for forecasting the propagation of coronal mass ejections (CMEs) in the heliosphere. Over the years, EUHFORIA has undergone significant development such as the creation of dedicated visualization tools and the continuous addition of advanced CME models. Among these, the realistic Fri3D model, as well as recently implemented toroidal models whose magnetic field distributions are derived using physics-informed neural networks (PINNs), to enable access to toroidal magnetic field distributions that are otherwise not analytically accessible or computationally expensive to obtain.
The most recent advancement is the coupling of EUHFORIA with the global coronal MHD model COCONUT (COolfluid COroNal UnsTructured). While EUHFORIA traditionally injects CMEs at 0.1 AU, COCONUT extends the simulation domain down to the solar surface, providing a self-consistent solar wind background derived from observed magnetograms. This coupling enables us to track the full evolution of a CME from its solar origin through the corona and into the heliosphere, improving our understanding of CME-solar wind interactions and their eventual geo-effectiveness.
The complexity introduced by the addition of these new capabilities brings new challenges for operational and research use. Therefore, I will also present recent efforts to streamline and automate the full COCONUT+EUHFORIA simulation chain, with the goal of making it more accessible, user-friendly, and easier to maintain and develop in the future.
