      Hi all, I'm trying to simulating a hypervelocity impact case with a bullet of two sections and a target of two different materials. But whenever I pack selected object, only the last object shows the material and the rest just won't show. How can I fix this? Or is this just how it is designed?

       

      Plus, if this is how it is designed. How to place Gauge points on those "empty" objects?

      The problem has been solved. 

      To solve this, just build all the objects first, then save and exit Autodyn. After that, all the material and SPH particle can be assigned.
