Magnetic Flux Density

The node adds a boundary condition for the magnetic flux density. The following equation defines the normal component of the magnetic flux density using a magnetic flux vector B0:

(5-1)

Using this boundary condition specify the normal component of the magnetic flux density at the boundary.

Alternatively, specify an inward (or outward) flux density using the following equation:

(5-2)

Using this formulation, it is possible to specify the normal component of the magnetic flux density as a scalar.

Magnetic Flux Density

Select a of the boundary condition to use— (the default) or :

•

For it defines the boundary condition according to Equation 5-2. Enter a scalar value or expression for the normal component of the Bn (SI unit: T). A positive value represents an inward flux.

•

For it defines the boundary condition according to Equation 5-1. Enter a value or expression for each component of the B0 (SI unit: T) in the corresponding fields.
