[Pw_forum] problem with convergence during SCF-procedure

[Alexej Mazheika]

Dear all

I perform the calculations of surface with adsorbed cluster Ag4/TiO2 and
have a problem with convergence during SCF-procedure. It does not converge.
In order to eliminate it I tried the shown methods in the user_guide: to
decrease mixing beta, to increase mixing ndim, to increase ecutwfc and
ecutrho. But it didn't help me. Is there any other methods to solve such
problem? The input file is here attached.
