Subject: [Pw_forum] Convergence problem for relax calculation 

Dear QE users, 

I am a beginner in electronic structure calculations and I have been trying to 
do relax calculations for my system. The input and output files are attached 
along with this mail. My calculations are not converging and I have tried a 
number of changes discussed on our forum earlier. I have changed the value of 
mixing_beta from 0.7 to 0.3, I have also increased ecutrho from 160 to 240 to 
320 as I am using ultrasoft pseudopotentials. But all my efforts have been 
futile till now. I would be extremely thankful if anyone could suggest me 
something which can help my calculations converge. 

Thanks
