Ansys Maxwell error when moving a magnetic core and a copper cylinder with a hole

AI Thread Summary
The discussion revolves around an error encountered in Ansys Maxwell when attempting to simulate the movement of a magnetic core and a copper cylinder with a hole. The error message indicates issues with handling a multiply connected region for eddy currents, specifically mentioning the need for proper band definition and container wrapping for moving objects. The user seeks assistance in resolving this error and requests a screenshot of the geometry to better understand the setup. Clarification on the geometry and movement is essential for troubleshooting the issue effectively. The conversation emphasizes the importance of accurate modeling in simulation software to avoid such errors.

Hello.
I have a magnetic core and a copper cylinder with a hole. I ask the cylinder to rotate and the magnet to move from left to right. I want to calculate Foucault currents in a copper cylinder, but an error appears.
"Failture in handing multiply connected region to eddy current. 1. Band definition. 2. Moving object in the band should be wrapped by a container object"
I Need a help.

Were you able to figure this error out yet?

Can you post a screenshot of the geometry and the movement? I'm not able to tie your description of the geometry to the figure that I see on your screen...
 

Thread 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...

Thread 'Electromagnet magnetic field issue'

Hi Guys We are a bunch a mechanical engineers trying to build a simple electromagnet. Our design is based on a very similar magnet. However, our version is about 10 times less magnetic and we are wondering why. Our coil has exactly same length, same number of layers and turns. What is possibly wrong? PIN and bracket are made of iron and are in electrical contact, exactly like the reference design. Any help will be appreciated. Thanks. edit: even same wire diameter and coil was wounded by a...

Thread 'Beauty of old electrical and measuring things, etc.'

Even as a kid, I saw beauty in old devices. That made me want to understand how they worked. I had lots of old things that I keep and now reviving. Old things need to work to see the beauty. Here's what I've done so far. Two views of the gadgets shelves and my small work space: Here's a close up look at the meters, gauges and other measuring things: This is what I think of as surface-mount electrical components and wiring. The components are very old and shows how...
