Use of AI to speed up numerical simulations: application to the design of superconducting tapes for energy and medicine domains


Superconducting tapes are used in superconducting high-power devices, such as cables, fault current limiters, transformers, and superconducting machines such as motors or generators. They are also used in coils for magnetic-field generation, such as high magnetic field for fundamental research, proton therapy or fusion power. This project focusses on the development of numerical tools based on artificial intelligence to emulate 2-D and 3-D partial differential-equations solvers in the time domain and to apply these techniques to thin-film multilayer structures with nonlinear properties, such as superconducting tapes, in order to decrease the computation time with the end goal of designing the best superconducting-tape architecture considering variations in tape properties at the millimetre scale. Polytechnique Montréal will provide expertise in materials science and modelling and the National Research Council will provide expertise in AI and machine learning for simulation.
