We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

In Autodyn Standalone, hyperelastic materials can only work with unstructured mesh. They do not work with structured mesh, i.e., IJK based mesh. 

If the parts in your Autodyn models are in structured mesh, you can click on Import from the top pull-down menu and then click on Convert IJK parts to Unstructured. See the picture below.

Once these parts are in unstructured mesh, you should be able to assign hyperelastic material models to these parts.
