How to set poloidal currents in ANSYS Maxwell

      Hi guys,

      I am facing a problem in giving as input in ANSYS Maxwell, a current that flows poloidally as in the picture.

      The solid has an offset from the global coordinate system, and in order to have the section where the current flows I had to set a relative coordinate system.

      I can give the current, and it seems that ansys evaluate the conduction path correctly.

      Nevertheless, it always stop giving me the error: "Current leak to the air".

      I do not know how is possible.

      Does anyone know a possible solution?

      Cheers,

      Hi, @Aliosha,nMay I ask if your current is at a cross-section of a closed loop conduction path? The conduction path has to be composed of all conducting material. Otherwise you need to assign current at two cross sections at the two end of an open conduction path. Would you like to share more details about your model (especially the coil configuration)?n

      Hi, sorry for being late in answering but apparently your response alert was in my spam.nYes the current is at a cross section of a closed loop conduction path. As you can see from the figure above the current flows poloidally in its loop from the outer section to the inner section. nIn reality what I am trying to simulate is not a coil in the real sense, it is just a portion of a structure where I know a-priori that there is a current flowing in there.nI am struggling with this problem as ansys tell me that there is a leak in the air, while it recognize perfectly the conduction path.nCheers,nn
