1 These are the nonzero field components. For Cartesian coordinates, these are indexed by x, y, and z; for cylindrical coordinates, r, φ, and z are used. 2 Custom studies (for example, Eigenvalue) are also available based on the physics interface. 3 It is a multiphysics interface that couples the Magnetic Fields interface and the Heat Transfer interface. Other multiphysics interfaces related to the AC/DC Module are not shown in this table.
