[HYBRID] GENE/GENE-X user training and tutorial

This training event offers an in-depth, hands-on introduction to GENE and GENE-X - two state-of-the-art Eulerian gyrokinetic plasma turbulence simulation codes widely used in the fusion research community. Both GENE and GENE-X are designed to solve the five-dimensional (5D) gyrokinetic equations that govern microturbulence in magnetized plasmas. Despite their shared physics foundation, the two codes are tailored for different modeling needs and computational strategies.

• GENE (Gyrokinetic Electromagnetic Numerical Experiment) is a delta-f Eulerian code that uses field-aligned coordinates, making it especially suitable for high-resolution studies of plasma turbulence in both the core and edge regions. It supports simulations at ion and electron gyroradius scales and can operate in both flux-tube and radial-annulus geometries. GENE is well-optimized for linear and nonlinear studies, offering advanced physics models and diagnostic tools.
• GENE-X, an extension of GENE, is a full-f code developed for simulations that cross the separatrix into the scrape-off layer (SOL) and beyond. It employs a flux-coordinate independent (FCI) grid approach, allowing for flexible mesh generation and better handling of complex magnetic geometries and boundary conditions.

Both codes are highly parallelized, capable of running efficiently on large-scale computing systems using CPU or GPU architectures. This allows users to perform computationally demanding simulations relevant to present and future fusion devices such as ITER and DEMO.

The event is addressed to plasma turbulence specialists and/or PhD/Master students, who want to learn (or improve their knowledge of) corresponding GENE/GENE-X simulations skills.
