• •Systems simulation used for fast-running multiphysics models of fusion components.•CHIMERA provides a platform to validate different simulation approaches.•Thermal, fluid and EM loads of a CHIMERA sample have been coupled together.•In future models’ additional physics will be added, and ran probabilistically.Critical to the successful design of fusion reactor components is the development of coupled simulation models, capable of conducting efficient whole system design optimisation and virtual component qualification, under conditions which cannot be readily tested. Additionally, successful lifetime monitoring and predictive maintenance of fusion components through diagnostic measurements will be limited due to restricted accessibility and operation in a harsh environment. There is therefore a need for a component digital twin, which combines data from the physical instrumentation with simulation to provide abundant virtual diagnostics in real-time. CHIMERA (Combined Heating and Magnetic Research Apparatus) is a unique, multi-physics fusion component loading facility under construction at the UKAEA Yorkshire site. CHIMERA will be used as a testing platform to develop and validate the virtual test and digital twin capability. Initial efforts are focussed on the post-commissioning testing, where the first experimental data will come from, with models of the commissioning sample under test (CSUT) being developed. A systems simulation approach has been adopted covering hydraulic, thermal, electromagnetic, and mechanical domains. Each domain and section of the system are linked through fast-running surrogate models. This model forms the foundation for future developments to include probabilistic simulation, uncertainty quantification and real-time tracking alongside the physical asset.
