[Pw_forum] a question about cppp.x

[vega lew]

Dear sir,

I got another question about cppp.x.

when I want extract the trajectory from the cp.x, I find there
is something wrong.

here is my input file of cppp.inp,
prefix = 'cp_molecular' ,
fileout = cppp.out
outdir = '/disk5/nanjing/vega/cpmd/150/'
ndr = 50,
ldynamics = .true.,

when I use "ldynamics = .true.," to the input, the error was warning like
this.
"Error: dynamics requested, but only one frame"

but there is some trajectories written by cp.x. from the dynamics process of
600 steps to 800 steps. (iprint = 100,isave= default, steps before 600 is
used for reaching the GS and make random to the unfixed atoms and further
reaching the GS and several steps for verlet dynamcis both electronic and
ionic without temparature) could you tell me how to cope with this?

thank you for your attention.

best wishes,

vega
