Reply To: Modeling Rubber1 material on Autodyn

[Chris Quan]

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.
