What are the things that I've done wrong in this simulation?

Hello, all.

I am doing a explicit analysis in Radioss solver, a drop weight impact test on composite plate. It can completely run but when I look at the result. It doesn't show any animation. So, I will attach the file for anyone can check. Please help me.

you are using /INIVEL, but as all nodes of the impactor are attached to the /RBODY, you need to apply the velocity to the /RBODY main nodel.

Applying to the secondary nodes will not transfer the kinematic to the main node.

I hope this is helpful

Thank you so much. Now, the animation can play but it does not go and reach the plate. It go down just a few second and bounce back to the top.

How can I solve this? Which parameter I have to change to make it drop to the plate?

Thank you in advance.

I suggest you look into this example for the boundary conditions.
