Hello All,

I am trying to simulate the magnetic field from a current-carrying line.

Attached is my file.

I tried to follow one of the example given by COMSOL, but somehow I am encountering an error.

I already set the current input and the ground to coincide with the air boundaries, so I dont know what is wrong.

Any help is appreciated

Woo-Yeong,

To get rid of error, assign some small non-zero electrical conductivity to air.

Regards,

Sergei
