How to add external current density

Please login with a confirmed email address before reporting spam

Hi,

I'm trying to do something I think should be very simple and have been unable to so thus far. I'd like to study the response of a circuit to a magnetic field. This field can be effectively produced by a homogenous time dependent current density flowing through the ambient space that the circuit is in.

So I'd like to just try to get a specific current density to flow through a specified volume of space that I can then put the circuit in. I've tried browsing through the magnetic fields interface, and can't find out how to just specify a current density. I've also looked through user manual it it has been not very helpful. I was hoping someone would have suggestions or a source they can direct me to?

Thanks, Henry

Henry,

External Current Density on the domain level is available in the (mf) physics interface. Just right-click Magnetic Fields (mf) node and you'll see it, as shown in the attached image.

Regards,

Sergei
