Solver gets to grips with 3D motion
The upcoming 6.14 release of MagNet will contain a novel 3D transient-with-motion solver.
The upcoming 6.14 release of MagNet will contain a novel 3D transient-with-motion solver This new solver includes coupling to the mechanical equations of motion, so that the movement of a component of a device (such as the rotor in an electrical machine or the slug in an actuator) is accurately simulated

Upgrade for electric field simulation
Software supports nonuniform voltage distribution to accurately represent the operating conditions of devices such as larger scale power transformers or electrical bushings.
As with the 2D transient-with-motion solver (which has been in successful use for over three years), the mechanical effects of viscous friction, inertia, mass, springs and gravitation, as well as constraints on movement imposed by mechanical end stops, and arbitrary load forces specified as a function of position, speed, and time, are all included in the simulation.
However, with the 3D solver, the field equations are solved in three dimensions, and so cover applications without translational or axial symmetry, such as end effects and skew in electrical machines.
Like its 2D counterpart, the 3D transient-with-motion solver only remeshes the region immediately surrounding the moving component.
Remeshing this relatively small and simple region is quick, and with this approach, no additional constraint equations need to be solved, which keeps solution times short and memory requirements low.
Popular applications for the 3D transient-with-motion solver are expected to include electrical machines (claw-pole, induction motors, switched reluctance, brushed and brushless DC, as well as linear devices), actuators, levitation systems, braking systems, magnetic bearings, loudspeakers, and electromechanical shakers.
