Physical properties of a vertex for problems of stress analysis.
Details
the LabelVertexSA object represents a physical data applicable to the vertex label for
stress analysis problems.
When you need to set or modify physical parameters for the block label, you have to get the LabelVertexSAobject using the Content property of the Label object, modify the LabelVertexSAobject using
its properties and then put it back in the Label object assigning your LabelVertexSA
to the Content property of your Label object.
The LabelVertexSA object provides a way to specify an external concentrated force applied
to the vertex, constrain conditions, and an elastic support.
The concentrated loads are defined at vertices as two components (ForceX and ForceY)
of the corresponding vector.
Rigid constraint along the vertex is specified by the prescribed displacement as a
constant (FixedX and FixedY).
Elastic support condition describes a vertex subject to springy force, which is
proportional to the difference between actual and predetermined displacement. The
elastic support condition is characterized by the predetermined displacement and the
support elasticity.
Coordinate components of the constraint condition and surface force are treated as polar or
Cartesian ones depends upon the value of Polar property.
Here is the complete list of properties that the LabelVertexSA object provides in
addition to the methods and properties from its base class LabelVertex.
