[Pw_forum] norm conserving

[ali kazempour]

Dear all
For first step calculation, we know that the optimization of ecut and kpoint is necessary . But I use norm conserving pseudopotential  that the check of convergency with respect to total energy is time consuming. Is any parameter except total energy that can i put treshold on its convergency or not?
thanks  a lot
