3D COMSOL model for CORC cables

This model was shared by Sofia Viarengo, Politecnico di Torino.

The model is a full 3D CORC cable: the T-A formulation has been coupled to a thermal module. The model is time-dependent and calculates current density, field distribution, and temperature in the superconductor in presence of transport current or background field. The electric resistivity of the superconductor is model through a power law: the dependence of the critical current density on the magnetic field and the temperature is also considered. A new boundary condition is imposed in a strong form allowing the current distribution and re-distribution of current among different tapes and layers of a CORC® cable (that is one of the main model issues to tackle for those cable) if any thermal or magnetic disturbance happens.
