The simulation of quenches in superconducting magnets is a multi-physics problem of highest complexity. Operated at 1.9 K above absolute zero, the material properties of superconductors and super-fluid helium vary by several orders of magnitude over a range of only 10 K. The heat transfer from metal to helium goes through different transfer and boiling regimes as a function of temperature, heat flux, and transferred energy. Electrical, magnetic, thermal, and fluid dynamic effects are intimately coupled, yet live on vastly different time and spatial scales. While the physical models may be the...
