Hello
I am doing the Magnetic Gear 2D tutorial and the results seem to be different with that provided. There seems no flux densigty in steel poles area.
It is stated in the tutorial in page 19 that it just adds air to Component 1but doesn't state any areas. However, it is impossible to put no materials for some areas otherwise it would raise errors. So I am wondering if there are any problems.

Hi Jianbin,

When you add the first material i.e. Air in this example, it will automatically add Air material to all the domains. In the next step, once the second material: Soft Iron (without losses) in this example is added, the existing Air will be overridden with Soft Iron in Domains 22 and 49.
Hope this helps.

Best Regards,
Nirmal
