Hi all,
I need to analyze Electromagnetic force of racetrack coil with time dependent. To make this model, I use external current density. It has been confirmed that the external current density can be properly analyzed by time dependent analysis of circular coil. By using like those formula. Ix = I0-y/sqrt(x^2 + y^2), Iy = I0x/sqrt(x^2 + y^2), Iz=0
Now I try to analyze racetrack coil using external current density but I can't. I attached the file. Please give me your help and advice.
Thank you
