Dear all, I am simulating a pm-motor in rotating machinery magnetic(rmm) in comsol. In the process of my simulation, I have met the questions in the title. I have done with in 2 ways. Case one, I imported my entire model with the dxf file. In this way,I cannot created the identity boundary pairs but the magnetic insulation boundaries are correct. Case two, I draw the stator part and rotor part in a file. And I imported the file in comsol. The rest parts of my motor I drew in comsol. I successfully created the identity boundary pairs but the magnetic insulation boundaries are not corrected. The magnets were with the magnetic insulation,I tried defined another magnetic insulation boundaries to override the boundaries that automatically selected in comsol. When I computed,the the magntic flux density of magnets were nearly zero. Anyway, if you met the similar quetions, hope you can write down your opinions or share your ideas generously. I show my sincere thankfulness to you. I uploaded a picture that the physics, it cannot change the boundaries it automatically made. The units in the picture cannot make changes.
Regards Joey
