Velocities
Section System::Velocities
Type block
If XYZVelocities, PDBVelocities, and XSFVelocities
are not present, Octopus will try to fetch the initial
atomic velocities from this block. If this block is not present, Octopus
will set the initial velocities to zero. The format of this block can be
illustrated by this example:
%Velocities
‘C’ | -1.7 | 0.0 | 0.0
‘O’ | 1.7 | 0.0 | 0.0
%
It describes one carbon and one oxygen moving at the relative velocity of 3.4 velocity units.
Note: It is important for the velocities to maintain the ordering
in which the atoms were defined in the coordinates specifications.
