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. The number of bands is the one set by ELPH_NBANDS which can in some cases be different from NBANDS. If both are set, both outputs are written.
