Hi,
I'm modelling an eddy current testing probe using the AC/DC module. It essentially consists of a transmitter coil with an applied input current and also a receiver coil which will have an induced voltage. I'm modelling both coils in 3D using the multi-turn coil domain.
I've got the actual probe and I've been testing the model experimentally, but so far I haven't been able to get the model to agree with experiment. The reason seems to be that there is resonance in the receiver coil near the frequencies that I'm interested in, but COMSOL isn't taking that into account. Does anyone know if there is a way to model the coils so that I can find the induced voltage across the receiver near the resonance frequency? Or are there any useful tutorial models I could follow?
Thanks,
Neil
