Hi All, amass(1)=100 and amass(1)=50 both give the same phonon frequencies.
This means, amass is read from the PAW file and not from the input phonon file. That is not useful for the case where one wants to change the atom mass manually to see how phonons shift with mass ratio. Could anyone please say to me where I can overwrite this default mass value and put an artificial mass value as I wish. Thanks in advance, Yours sincerely, Suza W.
