In addition to the infrastructure software, a wide range of physics models used extensively in the fusion modelling community have also been made openly available. This includes SOLPS-ITER (for the modelling of edge plasmas, principally composed of B2.5 and EIRENE), SOLPS-GUI (a graphical interface for SOLPS-ITER), DINA Plasma Simulator (for modelling tokamak scenarios) and a Heating & Current Drive Workflow (HCD-WF). The institutions that own the intellectual property for these codes (Max-Planck-Institut für Plasmaphysik, Forschungszentrum Jülich, Fusion for Energy, and the Plasma Simulation Center) are gratefully acknowledged for their support. Fully aligned with this ITER-led effort, many research institutes from the ITER Members and non-Members have also made their plasma simulation codes openly available under open-source licenses (such as METIS, CHEASE, GACODE, NICE etc.), greatly enhancing the open access of plasma simulation codes to the wider fusion community, including privately funded initiatives.  

The IMAS software set available as open source will gradually be expanded moving forward and enriched with additional documentation to help users find the appropriate IMAS software for a given use-case. Near-term steps include the release of synthetic diagnostic models to simulate the expected measurements in tokamak plasma scenarios and support the inference of plasma properties.

And of course, contributions in all forms (source code improvements, bug reports, documentation, installation recipes on different platforms, etc.) by the worldwide fusion research community are very much welcome for all these different software packages.
