Vertex Attributes: Translational Stiffness

Description

Assigns translational stiffness to selected vertices using three orthogonal components and a coordinate system.

When the geometry is meshed, the node created at the vertex will inherit the translational stiffness attribute (see Node Attributes: Translational Stiffness).

Vertex translational stiffness attributes are not interpolated between vertices.

Translational stiffness attributes are freedom case dependent.

Dialog

Translational Stiffness X / Y / Z

Three principal components of a translational stiffness matrix defined in the selected coordinate system.

Drawing Direction

The direction in which the attribute symbol is drawn along the axes.

The drawing direction is used only for graphical display purposes and does not affect the solution.

Coordinate System

The coordinate system (UCS) in which the principal translational stiffness components are defined.

The translational stiffness attribute remains associated with the UCS in which it is defined. Subsequent changes to the UCS will change the resulting stiffness matrix.

In geometric nonlinear analysis, the principal directions of the attribute's stiffness matrix are not updated.
