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 is presented.
