Hi,

I'm trying to simulate the behavior of a magnetic flux with permanents magnets in a iron piece. I've drawn this piece using the Comsol's CAD. In my piece, there're some empty parts. I just want to know how to make these empty parts becomes air.

Thanks.

When drawing do not remove empty parts, but define them as air in the Materials library. I cannot reply better without seeing your geometry.

Best regards
