[Pw_forum] The effect of cold smearing on DOS

[mashiat alaaii]

Dear Paolo,
I did use cold smearing and the output shows the smearing contribution
(which is almost -0.01 RY (I don't know what negative sign means)).
However, my concern is the effect of cold smearing on DOS. Does using
"cold smearing" change DOS. If positive, I was wondering whether it
adds some specific parts to it or it changes DOS radically.
I really really appreciate your help.
Yours
Mashiat

if the code says "smearing is needed", smearing is needed.
Are you sure you used it? what the code uses should be
reprinted on output
