For the axis-symmetric problem, it should calculate the total power considering the distance from the axis. You get the total power in W.

For planar 2D, 1m thickness is considered. In this case, the value you get is power density = watt per meter.

Extend your BH curve into the saturation region or at least for higher H values.
It might be that Elmer is linearly extrapolating your curve.

Could you share a BH curve or even better an entire case as it is not clear where magnets are?

Hi,

Thank you for the suggestion. I think the solution is either numerical (modifying residual), changing material properties close to terminals, or figuring out how to set up the current distribution.

Hello Rich, The case runs without issues from a terminal. Elmer version - Rev: Release, Compiled: 2023-06-21 ElmerSolver highFreq.sif ElmerSolver lowFreq.sif Hello fjimenez, I know about setting potential. Also, fixed current density can be set through circuits. The current task is to find a solutio...

Hello, https://img001.prntscr.com/file/img001/fU42PWWrRY2L491w3A51Jw.png The current density can be set either as Electric Current Density = Real 100.0 for current density distribution on the terminal or Electric Current Density = -distribute 100.0 as the total current through the face. At low frequ...

Thanks, Rich, for offering help. The case is large, and the issue happens only on one computer out of many. So chances are low that you will reproduce it. These are a few ideas that we already tested: - Not enough PSU power - Version of Elmer More tests to do: - BIOS update - Changing CPU on the sam...

Hi,

Have you ever encountered a Blue screen (crash) in Windows while running Elmer in parallel?

I suspect MPI causes this because it is the only software with admin rights.

Also, if you know how to debug such cases, let everyone know.

Thanks!

Hello Matias,

A few days ago, there was a pull request with fixes for OF v9 and v10. I merged them just now.
Could you please check if it works with those changes?

Thanks.
