8.2 Nodes - Deformations

To control the graphical display of nodal displacements and nodal rotations, select the Global Deformations check box in the Results navigator. Table 4.2 shows the deformations of nodes in numerical form.

Image 8.8 *Results* navigator: Global Deformations

Image 8.9 Table 4.2 *Nodes - Deformations*

The displacements and rotations are listed by nodes.

Displacements / Rotations

The deformations have the following meanings:

Table 8.1 Nodal deformations
\|u\|	Absolute value of total displacement
u_X	Displacement in direction of the global axis X
u_Y	Displacement in direction of the global axis Y
u_Z	Displacement in direction of the global axis Z
φ_X	Rotation about the global axis X
φ_Y	Rotation about the global axis Y
φ_Z	Rotation about the global axis Z
