Hi
I am new to Comsol I have tried to follow the tutorial "Inductor in an Amplifier Circuit " and I am not able to find material Soft Iron (without losses) or don't have the tree of materials for AC/DC module.
But the most important is that I cannot commit the action "In the Model Builder window, right-click Magnetic Fields and choose the domain
setting Multi-Turn Coil Domain." because it does not exist in the right click menu. Have I not installed something?
What should I do to find out what's wrong?

I am using Comsol 4.3

Hi

strange, could it be that you do not have the ACDC module of Comsol ? or that it is "disabled" check your licences

Good luck

I think I have AC/DC module because I can see it in my physics and can add it to the model. Then I can specify ampere's law etc. but not the multi turn coil. But when I open the model downloaded from the website I can see that it has that condition added.

Hi

check your "Options licences", standard COMSOL has some ACDC features so an ACDC node is from my understanding normal. The modules in COMSOL mainly adds features to the existing general COMSOL multiphyiscs basis. I do not have the acoustic module (trying to get it as it's very useful) but I still can do some "simple" pressure acoustics simulations coming from the basic CM

It says AC/DC module in Other Products. I guess that's correct.

Hi
indeedif you se the ACDC checked you have the module, but then you should also see the multiwire domains, at least I do !?
