  Hello,
  I am trying to use "Rubber1" material in a lagrangian approach to model a blast load on autodyn, but it seems that it doesn't work as it shows this message:
  
  What do I need to do?

  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.
