Hello,
I am currently performing a coupled field analysis. It is an analysis of an Active Magnetic Bearing in APDL. In the coupled field analysis guide, it is mentioned that for Boundary conditions in a structural-electromagnetic and Structural-stranded coil analysis, the VOLT and EMF degrees of freedom need to be coupled. I have attached a scrrenshot from the guide for reference (Img1).
I would like get some clarity on this . Does coupling of VOLT DOF mean that I have to specify a voltage on a single node of the coil and the couple all the nodes of the coil or is it that I have to input a voltage to the entire coil component and also specify a coupling constraint? Could someone please explain this coupling procedure. I have attached an image of the geometry of the coil structure that I am using. Also, when it is said that VOLT and EMF degrees of freedom must be coupled, both voltage and emf has to be input or either can be input?
Screeshot of coil geometry attached.
I am also looking for this topic. I hope to explain this method, thank you
