COMSOL implementation of the H-ϕ formulation with thin cuts for modeling superconductors with transport currents

These models were shared by Alexandre Arsenault, Polytechnique Montréal, Montréal. These two models use thin cuts with the H-phi formulation in COMSOL Multiphysics 5.5 to efficiently model transport currents in superconducting materials. The magnetic scalar potential is set to be disc …

Coupled A-H formulation for magneto-thermal transients in HTS magnets

These models were shared by shared by Lorenzo Bortot, CERN. The two models implement a coupled A-H field formulation in FEM, solving for H in the superconducting tapes, and for A elsewhere. The tapes are represented either by means of 2D domains or 1D thin-shells. For the second case, …

New benchmark problem for electromagnetic modelling of superconductors: the high-Tc superconducting dynamo

The high-Tc superconducting (HTS) dynamo has recently been proposed as a new benchmark problem for the HTS modelling community. The benchmark geometry consists of a permanent magnet rotating past a stationary HTS wire in the open-circuit configuration and assumes for simplicity the 2D …

AC losses calculation in REBCO coils or stacks

This model can calculate HTS stack/coil with various applied current and magnetic field. Its greatest advantage is the calculating speed could be very fast. The model is calculated by integration method, which was first proposed by Brandt for HTS tape. Here it is extended to ReBCO sta …

ANSYS APDL codes for modelling the critical state magnetization current in REBCO tape stacks with a large number of turns using the A-V formulation

An iterative algorithm method, based on ANSYS A–V formulation, is developed to simulate the critical state magnetization current Jc(B,θ) in ReBCO tape stacks during the field-cooling magnetization. The computation speed is quite fast because the eddy current is not computed in non-sup …
