Physical properties of a block for problems of DC Conduction.
The LabelBlockCF object represents physical data applicable to the block label for DC conduction analysis problems.
When you need to set or modify some physical parameters for the block label, you have to get the LabelBlockCF object using the Content property of the Label object, modify the LabelBlockCF object using its properties, and then put it back in the Label object assigning your LabelBlockCF to the Content property of your Label object.
The LabelBlockCF object inherits methods and properties from its base class LabelBlock. In addition, it provides properties specific for the DC conduction analysis. Those are Kxx and Kyy properties that allow getting and setting the electrical conductivity of the media in (S/m = 1 / Ohm·m). Please note that with the LabelBlockCF object you are dealing with a conductivity tensor (not resistivity as in the corresponding dialog box).
You always have to set both Kxx and Kyy properties even for isotropic materials. If the Polar property is set to True, the Kxx component is considered as a radial and Kyy - as tangential component of the conductivity tensor.
Electrical conductivity can depend on temperature. The dependency of conductivity on temperature is given in tabular form, which is automatically approximated by a cubic spline. When the conductivity depends on temperature, the material is considered as isotropic.
