Physical properties of a block for problems of time-harmonic magnetics.
Details
The LabelBlockHE object represents physical data applicable to the block label for
time-harmonic magnetics problems.
When you need to set or modify physical parameters for the block label, you have to get the LabelBlockHEobject using the Content property of the Label object, modify the LabelBlockHEobject using
its properties and then put it back in the Label object assigning your LabelBlockHE
to the Content property of your Label object.
The LabelBlockHE object inherits methods and properties from its base class LabelBlock. In addition, it provides properties and methods
specific for heat transfer analysis. Those are:
Get and set the components of magnetic permeability.
If the optional parameter is False or omitted, the value is considered as a
relative permeability, otherwise as an absolute value.
Absolute values of magnetic permeability are measured in (H/m)
Gets and sets the amplitude (peak value) of applying field source for the label.
The exact meaning of the Loading value depends upon two factors:
1. Whether the label describes conductive area (Conductivity > 0), and
2. Whether the TotalCurent flag is set.
See the Remarks section for more details.
Gets and sets the electric conductivity for the label in (S). Conductivity should be
positive or zero. Zero conductivity is the case if you don't want to simulate eddy
current in this area.
Gets and sets the flag specifies whether the conductors with total current or
voltage applied are connected in series. See the Remarks
section for details.
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
permeability tensor.
Remarks
The method of applying sources is different for conductors and non-conductive areas. The table
below shows the possible options:
Conductive
Non-conductive
TotalCurrent = True
The Loading is the total number of ampere-turns (in A).
The Loading is the total number of ampere-turns (in A).
TotalCurrent = False
The Loading is the voltage (in V) applied to conductor's terminals.
The Loading value is the current density (in A/m2)
When the total numbers of ampere-turns of the voltage is applied, you can specify how QuickField
should consider several areas labeled with this label (if any). If the Serial flag is set
to True, several conductors will be considered as connected in series. Serial conductors are
carrying the same current and calculated current density could be different if their squares are
not equal.
Please note that with time-harmonic problems you always specify amplitude (peak) values for all
alternating quantities.
