[CP2K-user] Restart xTB geometry optimization/molecular dynamics

Dear Mauro,

in principle you can restart the calculation via external file by:

  RESTART_FILE_NAME ./path/to/file/*.restart

Therefore, you need a restart file of the time/optimization step, from 
which you want to restart the calculation. Did you print out a restart file?

As default, all parameters are now used from the external restart file (at 
which you can take a closer look) and not from the input file anymore. The 
calculations runs as if you have use the restart file directly as input 
(which you can alternatively also do). If you want some parameters to still 
be taken from the initial input file, you can change the corresponding 
RESTART_* parameter to .FALSE. in the section above .
