Simulating a B-dependent critical current in superconductors

Please login with a confirmed email address before reporting spam

Hello,
I had a quick look at the "ApplicationLibraries/ACDC Module/Other Industrial Applications/superconducting wire" model which simulates the time-dependent behaviour of a superconducting wire and the magnetic field penetrating into the wire. The model uses an E-J characteristic curve specified as a user function which gives 0 in case J<Jc, and a steeply rising value if J>Jc, where the critical current Jc is constant. In reality Jc is a function of magnetic field (besides temperature). Can this be added to the model somehow?
Thank you
Daniel

Hi Daniel,

yes this can be done. In COMSOL any quantity (like the conductivity) can be a function of several arguments, you could define such a dependence analytically or based on table data.

Best regards,
