Displacement Results interpreted

mdharrington

Just learning the software so bear with me.

When running an analysis on the course tutorial files, everything is fine and the model has a safety factor of 12, but the displacements using the show/hide deformed state seem wildly out of scale....the part is extremely bent.

Is it normal to exaggerate the deformed state of the part being analyzed and is there a way to see the actual deformation with the load applied

Hello there!

Congratulations on embarking on your Altair Inspire journey! It's a robust tool, and with dedicated practice, you'll surely become proficient in its use in no time.

Regarding the exaggerated deformations you're observing in the results visualization, rest assured, it's a common feature in structural analysis software. This exaggeration is intentional to aid in the visualization of the model's movement and bending under load conditions, which might otherwise be difficult to perceive. However, it's important to note that these exaggerated deformations do not accurately represent the true magnitude of displacement.

In Inspire, you have the option to view results in a true scale, which provides a more realistic representation of the deformation. This allows you to observe the actual displacement of your model under the applied loads.

To change the scale deformation factor in Inspire:

1. On the Structures ribbon, select the Show Analysis Results tool on the Analyze icon, if not already active.

   

2. Click the Hamburger icon () at the left end of the animation toolbar to change the animation settings.

    

3. Un-check the "Auto" box in the Scale by section.
4. Enter a custom value to change the scale of the animation. Generally the scale of a displacement is too small to see clearly, so auto scaling is enabled by default. True scale would be a custom value of 1.
   

More information about Animating and Recording Results, and a description of all animation settings can be found in this page.

Keep exploring Inspire's features, and don't hesitate to reach out if you have any further questions or need assistance.

Best,

R.
