Re: [Pw_forum] Fw: SCF convergence in magnetic system during vc-relax

Pang, when you advise to change mixing steps, are you suggesting to change  mixing_ndim or mixing_fixed_ns ?  I'm not sure the effect of either one, can you please explain?Turning off spin polarization might get to a different ionic ground state -- I'm starting from a converged ionic ground

have a look at the sg15 database for optimized normconserving vanderbilt pseudopotentials (onsvpsp) http://fpmd.ucdavis.edu/qso/potentials/sg15_oncv/ under elements/ you'll find for each element you want the pseudo in upf format ready to use in pwscf AND the input file (*.dat) that was used to

[Pw_forum] Huge esa when H2O background is added

2015-03-01 Thread huangxu1706
Hi, I'm using QE-5.1 to do LiCoO2 surface modeling in aqueous condition. I added H2O as background in relaxation pw.x calculation. However, the structure couldn't get convergence and the esa (estimated scf accuracy) are huge as following: estimated scf accuracy< 58.06563547 Ry

[Pw_forum] nscf not converging at high doping level

2015-03-01 Thread Winfred Mulwa
Dear all, I am doing DOS calculations at different doping levels in a 72 atom supercell. At 1% doping, the nscf calculation converges very well but at 2% doping, the calculation stops at the band structure calculation point with no error. Somebody assist, what might be the problem. Attached is
