[Pw_forum] CP.x and adiabaticity

[Bertrand SITAMTZE]

Dear all,

I performed several molecular dynamic runs but I  still
facing some difficulties in choosing the time step and
fictitious electron mass that help to control the adiabaticity.

I search the web and read some documents, but I still lack
a good paper that takes the problem in its practical aspect
(how to know if the time step should be increase or not, 
how to manage the electrons mass after the .evp file, etc).

Can somebody give me a hint?
