Frequently Asked Questions

Can I model non-linear bending of beam like components?

Yes, you can model the non-linear bending of a beam up until the material’s elastic load limit.

My model fails to solve, what are some areas I can look at?

If your simulation fails, please try one of the following:

Reduce the maximum order of the integrator to 1 or 2
Remove any damping factors specified for the NLFE components (set them to zero).
Try to increase the number of elements in your NLFE component
If you are modeling hyper elastic materials, you may want to try using the Neo-Hookean model before using the Yeoh or Mooney-Rivlin as these are more sensitive models and require accurate material constants from test data.

I attached my NLFE body to a fixed joint, but it does not behave as if it is fixed. What is going on?

Please see Forces, Joints and Motions with NLFE Bodies.

How can I contour the deformations for my NLFE component?

Currently, you cannot. Please see Post-processing: Generate Results for NLFE Components.
