AC/DC Module

The AC/DC Module sets the stage for the simulation and modeling the performance of resistors, capacitors, inductors, coils, motors, and sensors. Although these devices are principally characterized by electromagnetics, they are also influenced by other types of physics. Thermal effects, for instance, can change electrical properties of materials, while electromechanical deflections due to electrostatic attraction or magnetic fields need to be fully understood during any design process.

With functionality designed for the needs of the electrical and electromechanical engineer, the capabilities of the AC/DC Module span electrostatic, magnetostatic, and low-frequency, electromagnetic phenomena, with unlimited couplings to other physics.

When considering your electrical components as part of a larger system, the AC/DC Module also lets you couple your component-level finite element model to a SPICE model of a complete electrical system. You can then extend your analysis by running a single simulation of a mixed system of lumped and high-fidelity models.
