Physical properties of a block for problems of DC magnetics.
Details
The LabelBlockMS object represents a physical data applicable to the block label for
magnetostatic problems.
When you need to set or modify physical parameters for the block label, you have to get the LabelBlockMSobject using the Content property of the Label object, modify the LabelBlockMSobject using
its properties, and then put it back in the Label object assigning your LabelBlockMS
to the Content property of your Label object.
The LabelBlockMS object inherits methods and properties from its base class LabelBlock. In addition, it provides properties specific for
magnetostatic 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)
Alternatively you use the Spline property (see
below) to describe the permeability as a function of the flux density.
When the TotalCurrent flag is set to True, the Serial flag specifies
whether the conductors with total current applied are connected in series.
Serial conductors are carrying the same current and calculated current density could
be different if their squares are not equal.
With axisymmetric problems, if the total number of ampere-turns is specified, that Boolean
flag specifies that the current density in your coil varies inversely to the radius
rather than being distributed uniformly.
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
permitivity tensor.
Using Splines
Spline is an object representing the functional dependency of
one variable from another. The LabelBlockMS object can use the spline to represent the
magnetic field intensity as a function of the flux density. That is a magnetization curve of the
material. You use the Spline property to get or set the
spline to the LabelBlockMS object.
To get an existing Spline object you use the Spline
property. If the spline you need does not yet exist, the Spline
property returns nothing. In that case you have to first create a new spline using the CreateBHCuve method.
To enter or modify spline data you use methods and properties of the Spline object. When you are finished with spline data you have to
assign the Spline object back to the LabelBlockHT object using the Spline or the LoadingSpline
property.
