I am calculating the Lorentz force in a sheet metal near spiral coils. Transient current thru the coils have short period. So I am using the RF module instead of the AC/DC module.
In one example, I learned that I can setup a current density on the cross section of the coil. But for RF module, when I choose the cross section, which is a circle, there is only subdomain settings like electric parameters, magnetic parameters, initial values of A and E. I just can not find anywhere for current density.
I found out one option: to model the coil as lines without no cross section, which means I just need to model the coil as a point in a 2d axisymmetric model. But in this case how should I define the distance from sheet metal and coil considering the radius of the coil?
I am using V3.4. I searched thru the forum without answers about this.
Hope anyone can give me some advice.
Thank you very much, experts!
