there are two search functions, both linked and well visible in the
"Contacts" page of the QE web site.

Thanks for the fast reply!
This leaves me to the problem of the interpretation of the results.
Has anyone experience with the calculation of polymorphic molecular
crystals?
My energy differences of 120 and 240 kJ/mole are far too high for
polymorphs (see ?ref [1]).
Am I mistaken to equalize

Hello together,
I'm sure, this question has been already asked - but lacking a search
function for the pw_forum and not having found something using google,
I'm urged to ask this question to the list:
How do I convert the output of pwscf (which is in Ry) to kJ per mole?
Conversion to Joules
t's well hidden.

Dear all,
I have tested some hydrogen PP by calculating the hydrogen molecule. I
found that for some PPs the starting charge was not very close to two as
I respected. The results:
H.pbe-rrkjus.UPF : starting charge1.80759
H.pz-rrkjus.UPF : starting charge1.81576
11 matches
