Physical properties of a vertex for problems of heat transfer.
Details
The LabelVertexHT object represents physical data applicable to the vertex label for heat
transfer problems.
When you need to set or modify physical parameters for the block label, you have to get the LabelVertexHTobject using the Content property of the Label object, modify the LabelVertexHTobject using
its properties and then put it back in the Label object assigning your LabelVertexHT
to the Content property of your Label object.
The LabelVertexHT object inherits methods and properties from its base class LabelVertex. Here the LabelVertex's properties take the
following meaning:
Sets and gets the known value of the external current density at the vertex.
The heat source specified at a point of the xy-plane corresponds to a linear string-like heater,
which is perpendicular to the plane of the model, and is described by the generated power per
unit length. In the axisymmetric case the vertex heat source represents a heating circle around
the axis of symmetry or a point heater located on the axis. To incorporate both these cases a
total generated power value is associated with the vertex. For the heating circle, the total
power is connected with its linear density by the relationship q = 2pr×ql.
