[Pw_forum] help entreaty

[sprokuda]

Dear Paolo!
When in one run of the same script I get positive frequency, in the
other run - negative frequencies (on some points in BLZ), while other points are in good
agreement with exdperiment - you think it can be explained by some
features of solid states theory ? I don't think so. I strongly guess that it is a
prblenm of configuration of my computer ( mostly hardware), that' why
I'm asking about help.
Sincerely yours, Sergey Prokudaylo.
