Dear Tlyer,

One way to achieve this is to prepare the system with some MD run at a 
desired temperature.
Then you restart the MD from the generated .restart file, where you have ad 
hoc modified the velocities of the atoms that you want to accelerate.
Obviously in the EXT_RESTART section the restarting of velocities has to be 

Kind regards
