I get significantly different results compared to the (old) reference:




@AHaumer is this expected with the new parametrization?

[AHaumer]

@maltelenz I'll check in the evening.
Results of Electrical.Machines and Magnetic.FundamentalWave should be the same (with same parameters).

[maltelenz]

@AHaumer Apologies, I don't know what I did for the previous comment. I reran the experiment, and everything seems fine now. I must have made some mistake before.

So this seems fine for WSM.

LGTM. Let's fix this locally for all models that have some issues at least in one tool. We'll consider changing the default in MSL 4.2.0

[casella]

@maltelenz you have a green light from a library officer (the author of this PR) and from the Master of Ceremonies (yours truly), so I guess if this runs fine in WSL you can safely approve it, so we can merge it in. Thanks!
