I am doing coil simulation in 3D. I have a coil (9 turns). My task is i want to find coil inductance and A/C resistance at different frequncies. I was simulated at 100KHz and 1MHz frequncies. Problem is at 100KHz it is giving good results but when it comes to 1MHz it is giving bad results. Can any body know how to get good results at high frequncies. I metion my Simulations links below. Thanks in advence.

for high frequencies I suggest to use the RF modul and not AC/DC!
I do not have experience with it, but RF module takes all effects (displacement field) into account...
I am modelling a 3D coil, too. How did you model your coil? Did you model each wire, or is it just one domain.
I am looking for a way to model a multiturn coil domain using just one toroidal domain.
If the domain is electrical conductive (choosed copper as material) I seem to have eddy currents, because the domain behaves like a single turn domain. If the conductivity is set to zero, the solverproduces error message: can't find inital values...
Any suggestions?
Best regards
