VELOCITY = [logical]
 Default: VELOCITY = .false. 
Description: Determines whether the ionic velocities are written to the vaspout.h5 file during an MD run.
| Mind: This tag is only available as of VASP.6.4.0. | 
You can use py4vasp to read the velocities into a Python dictionary
from py4vasp import calculation
calculation.velocity.read()
or to visualize the velocity in the crystal structure
from py4vasp import calculation
calculation.velocity.plot()
