Dear Elham
I think usually, for gaussian smearing, 0.2eV is enough for relaxation and
0.05-0.01 eV is good for DOS and magnetic properties. You can always get a good
results by setting enough narrow gaussian smearing.

Subject: Re: [Pw_forum] Smearing Problem
Hi Dear experts pwscf
I have questions about this topic.
Prof. Nicola two solution suggested. For every solution for every calculation
must be relaxed or scf calculation?
This is so long calculation for big system for determine best smearing.
another Question about (-TS) is must be zero?
Which of them is Best smearing tag for calculation (Gaussian or mv or mp or fd)?
Thanks so much
Elham
