Dear Yun-Peng,Plz try to decrease mixing and perform some convergence tests for your cutoff energy to remove the oscillation of the energy! In addition, this oscillation could also be caused by the unreasonable smearing methods for metals.BestsFang Sent from YoMail < Peter Cybertron> 20

2015-09-11 Thread Youssef
Dear Yun-Peng, Generally non-collinear calculation is hardest to converge, but I can't figure it out without knowing your physical system nor without a complete scf file. But firstly, you should reduce your mixing factor instead of increase it , start with mixing_beta = 0.1 and compare.

Dear Peter (or Yun-Peng??), Two wild guesses: 1) Did you check that the cut-off energies employed are sufficient? 2) The 'mixing_beta' is very large; the smaller this value, the tighter the convergence. Well, up to some limit; I would try a value closer to 0.3 or so. (If your system has a b

Dear researchers I have been working on bilayer TMDC materials. I have been facing problems with projwfc package. Although, for monolayer 2D materials, I was able to extract PDOS and the simulation worked fine , whenever I tried a bilayer structure, the projwfc would give the following error:
