Recent EUROfusion Achievements in Support of Computationally Demanding Multiscale Fusion Physics Simulations and Integrated Modeling

Abstract

-Integrated modeling (IM) of present experiments and future tokamak reactors requires the provision of computational resources and numerical tools capable of simulating multiscale spatial phenomena as well as fast transient events and relatively slow plasma evolution within a reasonably short computational time. Recent progress in the implementation of the new computational resources for fusion applications in Europe based on modern supercomputer technologies (supercomputer MARCONI-FUSION), in the optimization and speedup of the EU fusion-related first-principle codes, and in the *E-mail: Irina.Voitsekhovitch@ukaea.uk This is an Open Access article distributed under the terms of the Creative Commons Attribution-NonCommercial-NoDerivatives License (http://creativecommons.org/licenses/by-nc-nd/4.0/), which permits non-commercial re-use, distribution, and reproduction in any medium, provided the original work is properly cited, and is not altered, transformed, or built upon in any way.

A fast tool for ICRH + NBI modelling within the EU-IM framework

“…The integrated modelling efforts started a decade ago (Imbeaux et al 2010;Strand et al 2010) and the backbone has now reached a level that massive exploitation has become possible. The EUROfusion's Integrated Modelling (EU-IM) framework is routinely applied for modelling present-day machines such as JET, as well as future test devices such as ITER and DEMO (Falchetto et al 2014;Imbeaux et al 2015;Falchetto et al 2016;Pinches et al 2018;Strand et al 2018;Voitsekhovitch et al 2018;Falchetto et al 2019;Romanelli et al 2019Romanelli et al , 2020. Likely the biggest application of the EU-IM framework efforts is the European Transport Solver (ETS) (Coster et al 2010;Kalupin et al 2012).…”
