Displaying deformations

To visualize the results of deformations, first click , and then select a chosen partial result from these options:

• Representation of the displacement in the global axis X-direction
• Representation of the displacement in the global axis Y-direction
• Representation of the displacement in the global axis Z-direction
• Representation of the global deformation of the structure
• Representation of the rotation angles along the global axis X
• Representation of the rotation angles along the global axis Y
• Representation of the rotation angles along the global axis Z
• Representation of the first buckling mode

In the display of the global deformation , you can see how the structure really deforms in 3D view. Of course, the scale of the deformation will magnify the deformation in comparison to the geometry of the structure itself. Important: global deformations are not available in for enveloping values. In fact, a 3D display of all possible states of deformation creates an enveloping cloud that cannot be represented by one or two lines.

These three icons , , apply only to bars and cut lines. Angular rotations are not available for surfaces.

To see the deformations along the local coordinate system, ask a detailed result of the bar/ cut line in question.

First buckling mode

In a second order analysis, the global buckling factor α_cr is calculated. A global buckling occurs if α_cr<1.

Using the icon you can see which elements will buckle. The displacements are scaled in such a way that an global buckling factor α_cr=1 is equivalent to a deformation of 1m. A deformation greater than 1m is in accordance with an overall buckling factor α_cr<1 (more info).

For modal analysis

After having performed a modal analysis, you can look at the results per eigen frequency (and accompanying eigen mode). Go to the Results Configuration and select the deformations . In the pull down menu below, you can select one of the eigen frequencies. You can animate the movement of the structure with :

• : play
• : pause
• : speed up
• : slow down
• : animate with the speed of the eigen frequency.
