Hi All,
I've been scouring the internet for an answer to this question, but I can't find anything about what I'm doing wrong.
I'd like to specify a certain magnetic field in a cylindrical air domain that is azimuthal (phi direction), and increases with the radius, so basically B=r x phi (the axis of rotation is the y-axis), up to numerical factors that are being ignored for now.
I've tried specifying the vector potential and magnetic field on the boundary, but none of these methods have worked. I've had success for a whole cylindrical domain, but when I try to do this for a slice (I will include something later that is symmetric every 36 degrees), I don't get the desired field. Can someone help me specify these boundary conditions so I get the desired field?
I've included the model below.
Thanks, Henry
