How to calculate the impedance of copper wire using AC/DC

Hi,
I am building the power cable using COMSOL AC/DC model. I want to ask if we have a copper wire, can we calculate the impedance of this wire? Should we use which interface(like es or ec)? should we have to use 3D model? Should we add some special constraint condition in physics? If there is any related examples, please share with me.
Thank you very much!
Best regards,
Bin

Hi Bin,
You could calculate coil inductance both in 2D and 3D. We have several examples available in the Applications Gallery, in particular the following examples in 2D-axisymmetry will be useful.
1. www.comsol.com/model/mutual-inductance-and-induced-currents-between-single-turn-coils-12653
2. www.comsol.com/model/mutual-inductance-and-induced-currents-in-a-coil-group-12679
3. www.comsol.com/model/mutual-inductance-and-induced-currents-in-a-multi-turn-coil-12687
Note that these examples are for the mutual inductance calculations using Single Turn Coil, Multi-Turn Coil and Coil Group feature. These features are also applicable to directly compute the inductance for a single coil or wire.
For 3D case, take a look at this power inductor example:

In addition, the following two blog posts will be useful here:
www.comsol.com/blogs/model-cables-and-transmission-lines-in-comsol-multiphysics/
www.comsol.com/blogs/computing-the-inductance-of-a-wire/
Hope this will be useful.
