Opera-3d Superconducting Quench Module
The quench module uses advanced FE techniques to model the highly non-linear transient behaviour of a magnet during a quench. Using an algorithm which couples the electromagnetic solution to the thermal and circuit solutions (to determine the currents in the coils), users can analyse the full quenching process.
The quench process
Full System Modelling
Opera-3d couples electromagnetic and thermal analyses to a circuit representation of the coil to calculate currents in the windings. When additional entities, such as a conducting former or shielding are required, the quench module will also couple to Opera-3d’s transient electromagnetic solver for a full solution.
By coupling the analyses, users can model the non-linear behaviour during the quench process and investigate in detail. With these results, users can investigate the effectiveness of the protection circuits and other devices (e.g. quench bands). They can also investigate the sensitivity of the magnet to a quench including secondary quenching of adjacent magnets by rate dependent losses.
Opera-3d can simulate magnets that comprise complex superconducting cables with high levels of anisotropy and non-linear behaviour. Users can model noth low-temperature (LT) and high-temperature (HT) superconductors. The quench module is supplied with material properties for Sumitomo HTS materials.
