  • The initial step towards JOREK integration in IMAS [Elektronski vir]
    Penko, Dejan ...
    JOREK is a non-linear magnetohydrodynamic (MHD) code which was developed with the intent of producing simulations of the MHD instabilities occurring in magnetically confined plasmas. Such simulations ... substantially contribute to the understanding of MHD instabilities such as Edge Localised Modes (ELMs) and are essential for the optimization of future fusion devices such as ITER. The code itself is already well established and has been validated on many occasions through simulations of MHD instabilities related to present fusion devices JET, MAST, ASDEX Upgrade, and DIII-D. JOREK is being adapted to work with the Integrated Modelling & Analysis Suite (IMAS) which is being actively developed and used by the ITER Organization, the EUROfusion community and other ITER Members. The list of codes adapted to use the IMAS Data Model is gradually increasing with examples including SOLPS-ITER and JINTRAC. The main goal of the integration of JOREK with IMAS is to enable interaction with the plasma scenarios stored in the IMAS databases in the form of Interface Data Structures (IDSs): input conditions can be read from the databases and nonlinear plasma states determined by JOREK stored. IDSs provide a uniform way of representing data within the IMAS framework and allow to transfer data between codes and to storage within larger integrated modelling workflows. In order to integrate JOREK within IMAS it is therefore necessary that transformation tools are developed to facilitate the reading and writing of the relevant IDSs, including the MHD IDS, with its underlying Generalized Grid Description (GGD). For this purpose, utilities have been developed that extract JOREK simulation plasma state, namely the grid geometry and computed physical quantities for each time slice, and then transform them to the appropriate output IDSs. In this article, these initial steps towards full JOREK integration into IMAS will be presented.
