Hi everyone,
I want to simulate a superconducting coil, but I only know how to set E-J character.
I don't konw how to add a current in the superconduct. The literature use I=integrate(J) to
constraint the edge of the superconduct.
So how to define the current density integral constraint on the surface of a conductor?
Any suggestion you make will help me. Thanks for reading this.

Hello, I have basically the same question: I would like to calculate the current distribution in a superconducting wire in the Meissner state, fed with a current significantly less than the critical current, i.e. the voltage at the wire terminals is zero (because the conductivity is infinite). Defining a "Current" Terminal (in the module "electrical currents") with rho_0 resistivity equal to zero does not seem to be accepted by COMSOL... Sorry for not being able to help you.
