I am creating a design in Maxwell 3D with 3 spools wrapped with wire.  The spools are going to be connected in parrallel.  The wire turns are modeled using a solid cylinder, splitting the cylinder and applying the current excitation to the planer face.  I also assign a boundary condition to the cylinder.  

How do we proplery assign the current excitations to all 3 coils to have them linked in the simulation?  I tried assigning each coil to its own current excitation but that produced some strange and seemingly quite wrong B field plots. Or is this the correct way?

Hi Eric,

You should use Transient or Eddy current solver, depending of your application. If I understand well, you have 3 windings corrected in parallel. In Maxwell, each winding can contain one or more wires. When you setup the Winding by default they are connected in series but in the low part of the window you can indicate if they are in parallel. In this case the excitation is specified in Maxwell.

Another option is to create the different windings in Maxwell, but use the External circuit to connect them.
