Adding a I vs. t curve to a coil

Please login with a confirmed email address before reporting spam

I want to simulate a pulsed DC coil. I have the current vs. time curve and I am wondering if COMSOL has the ability to add this to a multi-coil domain.

I was trying to follow the "coil_above_plate" example with multi-turn coil domain. However I don't understand what the values for the frequency do in the frequency domain study. When they type in "10[Hz],100[Hz],300[Hz]" in the example. I am wondering how this changes the current in the coils. So if I wanted the current in the coils to not oscillate at a given frequency but to decay like an RCL function how would I include this to the coil parameters.

Hi,
maybe you upload your model. It will be better to understand you.

Now, the multiturn coil domane from the example use numeric current calculation. You Need to lalculate this only one time in frequency sweep. Bacause it calculate only the currentdirection. The current value you give in multiturncoil setup. So for every freqency you have same current.
