Magnetic Field interface and the Moving Mesh interface are incompatible?

Please login with a confirmed email address before reporting spam

Hi everyone,

I've been trying to build a 3D model about magnets moving in a coil for some time but still haven't figured it out. I wonder if anyone has some experience of that.

I followed the 2D example and applied all the same boundary conditions but it just didn't work out. It seems like the Magnetic Field interface and the Moving Mesh interface are incompatible somehow.

An interesting phenomenon I found is that I can solve the stationary study without the Moving Mesh interface, but when I added the Moving Mesh interface even the stationary study failed though it's not included in the stationary study. The failure is due to convergence problem and I noticed that there is a discontinuity in the convergence plot and it suddenly goes up at some point.

Does anyone have any ideas of that?

Thanks,
Yong

Hi Yang:
I am currently working on this kind of model, and it can work out under stationery contidion(using assembly and continuity), however it doesn't work when i include moving mesh under dependent condition. I recently got a file that said this can't be done. I don't konw why. I'd like we have a communication privately. Thanks.
