Coil Construction in 3D

Recommended Posts

Hi to everyone!

 

I'm modelling a copper coil to check skin and proximity effect (first without the core).

When I was extruding the faces I found that it´s necesary to assign face regions in every conductor surfaces not to provocate short-cuts. Or on the other way, would be enough to define the material as "Solid Conductor Region Described By Impedance"?

 

Anyone knows another way to do the same easier?

Hi,
When you extrude the faces you will create a volumes, you don’t need to assign any face region just you need to create a volumes region and assign it to the volumes. If you use the same material for all the volumes you need just to create one volume region and assign it to the volumes.
To do it :
• Click on the physic (in the top, not in the data tree)
• Select volume region
• Select assign region to volumes
But if you have several region you need to create several volume regions and assign it for each volumes.
To see the losses and the proximity effect, you need to use a solid conductor region for each volume. Don’t forget to assign the internal and external terminal for each solid conductors.
To o dit :
• Click on the physic (in the top, not in the data tree)
• Select assign terminals to solid conductors
Best regards.

Thanks for your reply Abdessamed.

The thing is that, if you create an only conductor region, you'll need to insulate every turn not to create any short-cut as I describe in the image:
