Hello, sorry for the late reply, I was on holidays.

And can granoo be used to simulate planetary simulations, where velocities are upto 10-20 km/s and deformations are caused majorly by shockwaves?
Hum, not sure, this is no more ballistic velocities (~1000 km/hours) but "hyperveloce" velocities ! From my knowledge, materials do not react as solid at these velocities. You probably must take a look on hydrocodes and/or sph methods. But, to be honest, this is quite far from my scientific topic, so I am not 100% sure...
