ELPH_WRITE_TEXTVEL = [logical]
Default: ELPH_WRITE_TEXTVEL = .FALSE. 

Description: If set, writes the electron group velocities to a velocity human-readable text file.

Mind: Available as of VASP 6.5.0

The velocity file contains the following information:

# band kpoint spin direction energy(eV)  velocity
 1 1 1 1 e1 vel1
 2 1 1 1 e2 vel2
 ...
 8 1 1 1 e8 vel8
 ...

The group velocities are written in ev Å units in cartesian coordinates. This tag can be used independently of ELPH_WRITE_HDF5VEL. If both are set, both outputs are written.
