Hallo, i want to simulate rectangles multi-coil with symmetry. But my simulation is always failed. My study steps are, coil analytic and frequency domain. You can find my modell in attachment. I thins that the problem is maybe boundary-condition or output of coils. Thank you

Hi Yuqi,
You might want to go through this example to understand the symmetry setup for a coil. https://www.comsol.com/model/vector-hysteresis-modeling-20671
I am not sure if you can actually apply the single "Coil" feature to two physically disconnected domains or not. If this is not supported, you would need to apply to separate Coil features for each.

Hi, Nirmal, Thank you for this example. And i reference also this blog https://www.comsol.com/blogs/exploiting-symmetry-simplify-magnetic-field-modeling/
The Magnetic Insulation boundary condition — “cut perpendicular to J and parallel to B“ is suitable for my modell. I simulate now also only one coil feature. But i can´t get a good solution.
And firstly i used infinite element domain, because i thought that this coil don´t have closed loop. But under Geometry Analysis i can set Symmetry specification. What do you think about this?
