Dear Riccardo, it is not possible in the current implementation; it can be implemented but, as far as I know, nobody is working on it. If want it you can try to implement it yourself. More specifically, convergence of ecut depends only on the pseudopotentials, why don't you study it on some simple system (pure bulk, isolated atom, small molecule) and then transfer to your system? regards -- Lorenzo Paulatto SISSA & DEMOCRITOS (Trieste) phone: +39 040 3787 511 skype: paulatz www: http://people.sissa.it/~paulatto/ ---------------------------------------------------------------- SISSA Webmail https://webmail.sissa.it/ Powered by SquirrelMail http://www.squirrelmail.org/
