[Pw_forum] Getting value of mixing_beta

[Ganjar Kurniawan]

Dear QE users

I have doing vc-relax process of my system, when SCF process, the 
calculation is not converge after all. I think the problem is on the 
mixing-beta value.  (input and output file are attached)

my question is how to get the suitable value of mixing_beta for mine or any system without doing try and error calculation???

any response is greatly appreciated
