**Job Description**:
Finite Element models could be used for calculating such a response as all necessary geometry, and physics details could be included. To keep model and simulation time practical, a development of FE formulation to capture physics involved is needed for approaches with 2D conductor models accounting for strand twist pitch and/or cable transposition length or a 3D thin shell approach where the HTS layer is collapsed into a surface. Such conductor level response needs to be included in large scale quench protection models. A potential avenue is a conductor and/or winding level homogenization approach dealing with equivalent material properties. An alternative approach is a multiscale-multimodel simulation, where a detailed conductor level model is coupled and responds to a large-scale, magnet-level quench simulation model.
- Develop Finite Element models at conductor level (LTS and HTS; wires, tapes and cables) to simulate AC loss and magnetization response to transport current and/or an external magnetic field change.
- Develop methodology of coupling conductor-level simulations with full magnet size quench simulations. Homogenization and multi-scale approaches to be studied in detail.
- Where possible, verify developed approaches against analytical solutions and other quench simulation tools.
- Validate simulations with available measured data. Such validation will be done on the conductor or magnet level data depending on availability.
- Develop a methodology for abstracting the complexity involved and integrating with existing quench simulation tools or developing a stand-alone conductor-level simulation tool.
