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 s, capacitors, and electrical machinery. With this module you can run static, quasi-static, 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 in conductive media
•
Magnetostatics
•
Low-frequency electromagnetics
Material properties include inhomogeneous and fully anisotropic materials, media with gains or losses, and complex-valued material properties. Infinite elements 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 Materials Database and Nonlinear Magnetic Materials Database, 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 the other modules. For example, to find the heat distribution in a motor, first find the current in the s using one of the quasi-static interfaces in this module and then couple it to a heat equation in the main COMSOL Multiphysics package or the Heat Transfer Module. This forms a powerful multiphysics model that solves all the equations simultaneously.
The AC/DC Module also provides interfaces for modeling electrical circuits.
