What Can the AC/DC Module Do?
The AC/DC Module provides a unique environment for simulation of AC/DC electromagnetics in 2D and 3D. The module is a powerful tool for detailed analysis of resistors, inductors, capacitors, and electrical machinery. With this module you can run static, quasistatic, transient, and time-harmonic simulations in an easy-to-use graphical user interface.
The available physics interfaces cover the following types of electromagnetics field simulations:
•
Electrostatics
•
Electric currents
•
Magnetostatics
•
Low-frequency electromagnetics
Material properties include inhomogeneous and fully anisotropic materials, media with gains or losses, and complex-valued material properties. Infinite element makes it possible to model unbounded domains. In addition to the standard results and visualization functionality, the module supports direct computation of lumped parameters such as capacitances and inductances as well as electromagnetic forces.
Selected material data are provided with the module.
For detailed information about Materials including the AC/DC Material Library and Nonlinear Magnetic Material Library, see the COMSOL Multiphysics Reference Manual.
Like all COMSOL modules, there is a library of ready-to-run models that make it quicker and easier to analyze discipline-specific problems. In addition, any model you develop is described in terms of the underlying partial differential equations, offering a unique way to see the underlying physical laws of a simulation.
The AC/DC interfaces are fully multiphysics enabled — couple them to any other physics interface in COMSOL Multiphysics or other modules. The AC/DC Module contains predefined multiphysics interfaces to facilitate easy setup of models with the most commonly occurring couplings. For example, the Induction Heating multiphysics interface combines all features from the Magnetic Fields interface in the time-harmonic formulation with the Heat Transfer interface to model induction and eddy current heating.
The AC/DC Module also provides interfaces for modeling electrical circuits.
