Maxwell3d.assign_impedance(geometry_selection, material_name=None, permeability=0.0, conductivity=None, non_linear_permeability=False, impedance_name=None)[source]#

Create an impedance boundary condition for Transient or Eddy Current solvers.

This boundary condition is used to simulate the effect of induced currents in a conductor without explicitly computing them.


Objects to apply the impedance boundary to.

material_namestr, optional

If it is different from None, then material properties values will be extracted from the named material in the list of materials available. The default value is None.

permeabilityfloat, optional

Permeability of the material.The default value is 0.0.

conductivityfloat, optional

Conductivity of the material. The default value is None.

non_linear_permeabilitybool, optional

If the option material_name is activated, the permeability can either be linear or not. The default value is False.

impedance_namestr, optional

Name of the impedance. The default is None in which case a unique name is chosen.


Boundary object if successful, False otherwise.
