LabelVertexHT Object




Physical properties of a vertex for problems of steady-state and transient heat transfer.


The LabelVertexHT object represents physical data applicable to the vertex label for heat transfer problems.

When you need to set or modify some physical parameters for the vertex label, you have to get the LabelVertexHT object using the Content property of the Label object, modify the LabelVertexHT object 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:

Dirichlet property
as Double

Sets and gets the known value of the temperature T0 at the vertex.

Loading property
as Double

Sets and gets the known value of the heat source 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 = 2πr·ql.
