Hi!

I have been calculating energy barriers for certain chemical reactions
using CPMD. This I have done simulating the system in different fixed
positions. Fixed bond distances are put to the input-file in angstroms. So
my question is: What is the unit of the Force that is given to the
CONSTRAINT file during simulation? Is it a.u./a.u. or a.u./å? I haven't
found the answer from the manual, so I would be highly appreciated if
someone can help me with this small problem.

Regards, Jaakko Saukkoriipi
