Hi,
The 'Atoms moving too fast' problem is a tough one to diagnose without
knowing more about the system. Usually, some overcrowding causes one atom
to be repelled away at high velocity, but the cause for the overcrowding
can be due to several things. Can you explain the details of your
simulation?
