<div><div>Dear all<br><br>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. <br>
