[Pw_forum] Documentation on atomic velocities

[luisen]

Dear developers,

I am interested in using atomic velocities generated in previous MD runs 
in order to continue the MD calculation after a finished job (finished
either gracefully or abruptly).
I made a small program to compute the velocities from the positions and 
modified slightly the code in order to read the velocities from a file 
upon initialization if this file was present. It is however an ad-hoc 
solution.

I have seen in the last distribution (6.1) that there is the possibility 
of using a section in the input file named ATOMIC_VELOCITIES.

My question is if there is any documentation for its use, and if there
is any flag so as to output the velocities (in addition to positions) to
the output file, for later use as input in a subsequent run.

Yours,
