[Pw_forum] The scf can't converge

[wangwei]

Dear everyone:
         Recently , I am calculating a material ,but It can't reach my convergence standard.I have tried many times ,but failed.
My input file is :
 
                     ecutwfc = 50,
                     ecutrho = 500,
                 occupations = 'smearing',
                     degauss = 0.03
                    smearing = 'methfessel-paxton' ,
 /
 &ELECTRONS
                    conv_thr = 1.0D-8 ,
                 mixing_beta = 0.05 ,Please show me what's the matter ,Thank you !
