How can I simulate a helix coil with current in COMSOL Multiphysics?

Click For Summary
The discussion focuses on simulating eddy currents in a cracked steel circular rod using COMSOL Multiphysics, specifically with a helix coil creating an alternating magnetic field. The user has successfully modeled a spring coil in SolidWorks but struggles to apply a current through the coil in COMSOL. They seek guidance on adding the necessary AC/DC physics to their model to simulate the coil's functionality as in a laboratory setting. There is a suggestion to consult a dedicated COMSOL modeling forum for more specialized assistance. The user emphasizes the importance of this simulation for their work on Eddy current testing.

Hello !

I am using Comsol Multiphysics in order to simulate the eddy currents in a damaged/cracked steel circular rod, with a helix coil surrounded it and thus creating the alternativ magnetic field.

Actually, I am having a lot of problem in modelling it, mainly because I am new in using Comsol.

My first goal is to model the coil and put an alternativ current in it.

I managed to model a spring coil in Solidworks and import it in Comsol. But i cannot find how to put a current through the material in order to simulate the coil, like we can use it in a laboratory...

I guess, I have to do some things adding Physics, AC/DC, in the model. But what exactly ?

It would be incredible if you could help me, and guide me through my simulation. I need it in order to support my work about Eddy current testing. Of course, I would quote you as helpers and contact in my final work/report if you want.

Up ?
Nobody can help me ?

Maybe I am not in the right section ? I saw people here talking about comsol so I posted ... but i'll see
 
Please ?
 
You should look in a COMSOL modeling forum for the answers. There may not be anyone here who can help you.
 
Had my central air system checked when it sortta wasn't working. I guess I hadn't replaced the filter. Guy suggested I might want to get a UV filter accessory. He said it would "kill bugs and particulates". I know UV can kill the former, not sure how he thinks it's gonna murder the latter. Now I'm finding out there's more than one type of UV filter: one for the air flow and one for the coil. He was suggesting we might get one for the air flow, but now we'll have to change the bulb...
