[Pw_forum] car parrinello md

[Youssef Aharbil]

Dear Quantum espresso Community,

I want to use the car parrinello molecular dynamics code cp.x, but first i
want to ask some basics questions about this techniques:

1-What was the main motiviation  for the use of the car parrinello md  over
the conventional variable cell relation (bfgs and damp)?
2-Is it 100% ab inition md?
3-Is there any gain in therms of accuracy or speed vs the conventinoanl
vc-relax?
4-Can I use it on crystals?

Thanks in advance.
