Hi,
I am a new learner of COMSOL. I would like to learn how to create 5 uH spiral inductor. I have researched on website but I could not find the tutorial step by step. I saw only in AC/DC Library with spiral inductor. I would like to simulate with some thing like that model but with 5 uH. Please send me a link, tutorial or any book to understand more and I can create by my self? How to draw a geometry and put in that simulation?
Thanks,

Hello,
from my knowledge, you cannot define a structure's indcutance. You can define that for discrete elements in electric circuit interface, but not in the physics interfaces. On the contrary you can get the inductance of a structure calculated by COMSOL.
You might want to model the geometry of your inductor as close to the reality as possible and see if COMSOL calculates 5 µH (more or less).
You can use the helix primitive to model a spiral conductor. Or you try the single or multi turn coil domain in 2D axisymmetric mode.

Hi Eric,
So how can you model the geometry of inductor as close to 5uH as possible and how to use the helix primitive? I am a new learner of COMSOL. So please send me a guide , link or .... as detail as possible.

Hi,
this www.dl5swb.de/html/mini_ringkern-rechner.htm is a little tool that helps to design coils, toroids and solenoids (air core) . The user interface can be switched to English.
The helix node in COMSOL should be pretty self-explanatory, and you can always try and see if the results match your expectation.
Cheers
Edgar
