Hi,nIn my model, I have actually defined a force parameter for only 2 groups, not for all sections as below. I select each section one by one and apply current. my current is 9kA. my setup;(eddy current solver)nmax number of passes: 20npercent error: 0.01nrefinement per pass: 30nmin number of passes: 2nmin converged passes: 1nsolver: 50 Hznnonlinear residual: 0.0001nfreq sweep;nstart: 10 Hznstop: 1000Hznstep: 10 HznI assigned boundary as a vector potantial value:0, Phase:0nn
