Re: [QE-users] how to obtain random initial velocities with CP

2018-10-22 Thread Giuseppe Mattioli
Hi Paolo and Eduardo I would like to add some consideration, because I have a similar problem. I'm going to simulate the subtraction of one electron from a thermalized system. To do this, in previous cp.x versions (up to 4.3.2, AFAIK), it was possible to: 1) run a cp.x dynamics

Hi Eduardo apparently ions_velocities="random" does not set random initial velocities, but velocity rescaling. Not sure why. In any event: I am not sure that starting the CP dynamics from ground-state positions and electrons and nonzero initial velocities is a good idea. Paolo On Sun, Oct 14,

Does it happen in the last step, after a message like 'A final scf calculation at the relaxed structure' or 'lsda relaxation : a final configuration with zero'? or in the middle of the run? in the latter case, it is impossible to say anything unless the error is reproducible Paolo On Mon, Oct
