I try to solve resistive heating of the twisted power cable composing of 61 copper strands with 1m long in the perpendicular induction current, vector potential in AC/DC module.
I applied 100Arms with 60Hz to the cable and solved the magnetic field distribution. And then I selected 61 Cu strands at subdomain in subdomain integration and applied the Induced current density, norm.
The result was 110A*m and then devied 110A*m by 1m long, and 110A was obtained.
I think that the summation of induced current desity should be zero in 3D AC electromagnetic analysis.
Please let me know how to do in order for the summation of induced current desity should be zero in 3D AC electromagnetic analysis.
