Hi

Gravity will always be there so do not deact.

I would say use 3 steps

First Gravity on and no dynamic effects (so time int . off)

Second is a dummy step. Gravity on time int on. This (results) should be similar to the first step.

Third apply the dynamic impact load (gravity on of course here and time int. also on).

 

On another note, for impact do one need gravity when we have such a huge impact – consider for this to use LS-Dyna which is more suitable.

All the best
