A static magnetic analysis calculates the magnetic fields produced by one of the following:
Permanent magnets
The steady flow of direct electric current (DC)
An applied voltage
A moving conductor
An applied external field.
Static magnetic analyses do not consider time-dependent effects such as eddy currents. You can model both saturable and non-saturable magnetic materials, as well as permanent magnets in a static magnetic analysis.
The procedure for a static magnetic analysis depends on several factors:
Whether your model is 2D or 3D.
Which method you wish to use for your analysis. If your static analysis is 2D, you must use the vector potential formulation discussed in this chapter. For a 3D static analysis, you can choose between a scalar formulation (described in 3D Static Magnetic Analysis (Scalar Method)) or an edge element formulation (explained in 3D Magnetostatics and Fundamentals of Edge-Based Analysis).
If you are modeling two contacting bodies with dissimilar meshes (such as the air gap in a rotor/stator configuration). See Modeling Magnetic Contact for more information on modeling contact problems using surface-to-surface or node-to-surface contact elements.
The following 2D static magnetic analysis topics are available:
