Drop Test Simulation

Hello,

I am a Mechanical Engineering graduate student and I wish to simulate drop test of a human head form.

I have a few questions which I have enlisted below:
Can this kind of explicit dynamic simulation be carried out in COMSOL?
Which package supports this kind of simulation?
Is any specific license (Research/Academic, etc.) required?
Can we import a meshed geometry (model is meshed in Hypermesh) directly into COMSOL for analysis?

It would be of a great help if anybody could guide me on these.

Thanks,
Chandrika
