[Pw_forum] graphene scf calculation

[Vit]

Dear all!
I'm trying to plot graphene band structure as a part of computations of  
carbon based composites. But scf calculation for graphene can't achieve  
convergence. I've tried different mixing_beta, mixing_mode, degaus ant  
ecutwfc. The example input file is attached. Could you please tell me  
which parameters I should tune to achieve convergence?

Thanks in advance,
