This study presents the latest results of a 3D original Matlab code, developed for simulating in a fast fashion the charge/discharge of a EUROfusion DEMO toroidal field (TF) coil, by especially coupling both the electrical and thermal evolution e.g. in case of a quench propagation. We now report results with a higher accuracy (increment of nodes by a factor 2-10) reached also by means of high performance computing (HPC) at EPFL.
We show maximum temperature reached in the coil in case of several current extraction systems, different amount and distribution of bridging elements over the conductor length as well as their electric behavior (monotonic or two-fold resistivity regime).
