Required arguments

table

A sequence of sequences of Floats specifying the items described below in “Table data.” If type=ORTHOTROPIC and nonlinearBH=ON, the data specified in the table is for the first direction and table2 and table3 must be specified.

table2

A sequence of sequences of Floats specifying the items described below in “Table data” in the second direction. table2 must be specified only if type=ORTHOTROPIC and nonlinearBH=ON.

table3

A sequence of sequences of Floats specifying the items described below in “Table data” in the third direction. table3 must be specified only if type=ORTHOTROPIC and nonlinearBH=ON.

Optional arguments

type

A SymbolicConstant specifying the type of magnetic permeability. Possible values are ISOTROPIC, ORTHOTROPIC, and ANISOTROPIC. The default value is ISOTROPIC.

frequencyDependency

A Boolean specifying whether the data depend on frequency. The default value is OFF.

temperatureDependency

A Boolean specifying whether the data depend on temperature. The default value is OFF.

dependencies

An Int specifying the number of field variable dependencies. The default value is 0.

nonlinearBH

A Boolean specifying whether the magnetic behavior is nonlinear and available in tabular form of magnetic flux density versus magnetic field values. The default value is OFF.

Table data

If type=ISOTROPIC, the table data specify the following:

  • Magnetic permeability.

  • Frequency, if the data depend on frequency.

  • Temperature, if the data depend on temperature.

  • Value of the first field variable, if the data depend on field variables.

  • Value of the second field variable.

  • Etc.

If type=ISOTROPIC, and nonlinearBH=TRUE, the table data specify the following:

  • Magntitude of the magnetic flux density vector.

  • Magnitude of the magnetic field vector.

  • Temperature, if the data depend on temperature.

  • Value of the first field variable, if the data depend on field variables.

  • Value of the second field variable.

  • Etc.

If type=ORTHOTROPIC, the table data specify the following:

  • μ11E.

  • μ22E.

  • μ33E.

  • Frequency, if the data depend on frequency.

  • Temperature, if the data depend on temperature.

  • Value of the first field variable, if the data depend on field variables.

  • Value of the second field variable.

  • Etc.
