Magnet eddy current loss in Flux 3D

I checked the models. With Automatic formulations, Nodal finite elements, Second order for scalar and nodal vector variables in application definition in 3D is giving the same magnet losses as in 2D.

I have attached the updated model for your reference.

Thank you,

Hi Hallay,

Are the volume regions in both cases have the same volume?

Should be different.

Can you share the picture of the magnets? Also, do you have volumes assigned to each volume region?

Thank you,

Hello Lavanya

It's my miss, I don't assign magnet 2-8 in solid type.

Today I assign it and get 8 magnet eddy loss value.

Flux 3D magnet eddy loss value is 5.06 W and Flux 2D result is 1.68 W.

The ratio is 33.2 %.

Can you tell me why Flux 3D and 2D have different result?

The ratio 33.2% is the same in every case or case by case?

thank you

Hi Hallay,

I need to see both 3D and 2D models, to understand the reason behind the difference.

Is it possible for you to share it?

Thank you,

Hi Lavanya

Attachment is 2D and 3D file.

2D is whole model and 3D is half Model.

From my site, magnet eddy current loss in 2D is 1.66W and 3D is 0.88W(ignore huge value).

thank you
