In a Transient Magnetic 2D Axisymmetric simulation, a solid movable piece of steel is attracted upwards by the combined forces of permanent magnets and a coil. The coil is represented in the associated electrical circuit as a coil conductor with one turn, and its resistance is equal to that for one turn as well. Current through the coil conductor is imposed by a current source. Now, once the mover has moved half of the required distance, the magnetic circuit should start to act as a brake (or damper), rather than an actuator. Hence, by passive means, the speed of the mover should be reduced. I would like to achieve this by short-circuiting the coil, and using it as a solid conductor. However, this requires to switch from one electrical circuit implementation, to another one. In the second electrical circuit, there is no current source anymore, and the coil is represented as a solid conductor (to act like a solid piece of copper). Can someone explain how I can implement both of these situations in the same Flux simulation? @Flux support @lombard
