Comparison of Potential Dual Formulations Developed with Different Elements
To extend the field application of numerical simulation, it is necessary in many applications to consider the electric circuit. In 3D for the coupling between magnetic and electric circuit equations, the formulations in terms of potential are very attractive2,4,8. The electric formulation (A) can be used in many applications but it is necessary to determine three components. It may be noted that the necessity to impose a gauge condition permits to reduce the vector potential to two components if we use3,8 (U.w=0).
