Hi, I'm simulating a copper coil immersed in an air box. I'm using the AC / DC module, the physical magnetic fields and in the study the frequency domain steps and geometry analysis, I'm meshando the box with a sparse mesh and the coil with a thick mesh, I inserted the boundary layer on all the domains excluding the box because I want to display the skin effect of the current density. I would also like to visualize the resistance, the inductance and the impedance of the coil as a function of the frequency. I use two stationary solvers, one for geometry analysis and one for frequency domain. The study fails to converge or because the matrix has zeroes on the diagonal (and also inserting vanka does not go) or the simulation is impaled to 43% when it performs the factorization of the matrix. How could I solve it all? Thanks
