Re: [Pw_forum] Convergence issue in MoS2 super cell
Dear Mahendra Jalkhediya I have reached converged end(espresso-5.2.0 , in 38 iterations) in your input file by changing these parameter: starting_magnetization = 0.1D0 *to* starting_magnetization(2) = 0.1D0, smearing='gaussian'* to* smearing='mp', mixing_beta = 0.5D0 *to* mixing_beta = 0.3D0 and reduce ecut=30, ecurho=300, i am attaching the input file.

Re: [Pw_forum] Convergence issue in MoS2 super cell
Dear mahendra Do you use mixing mode=`local-TF` ? If you deal with a mono layer you have to use that in &electron card Set ecutrho 5 times of ecutwfc. If these not work reduce mixing beta value.

Re: [Pw_forum] Convergence issue in MoS2 super cell
Dear Mahendra Jalkhediya by the way, adding some bands also ( nbnd command) may effect the result. a couple of days ago I could handle converge problem for slab by changing these parameters; nbnd, mixing_beta, mixing_mode, smearing, degauss, pseudopotantial, atomic position and lattice vectors. 2015-07-21 23:28 GMT+03:00 Mahendra Jalkhediya < jalkhediya.mahen...@gmail.com>: > Dear Giovanni Cantele and Bahadır salmankurt > *I will modify my input file as you suggested and will update you > what happens.* > > *Regards* > *Mahendra Jalkhediya* > *IIT Kanpur* > > On Wed, Jul 22, 2015 at 1:15 AM, Giovanni Cantele < > giovanni.cant...@spin.cnr.it> wrote: > >> sorry, I meant “only GAMMA point” but the automatic corrector did not >> agree!! >> >> Giovanni >> >> >> > On 21 Jul 2015, at 21:39, Giovanni Cantele < >> giovanni.cant...@spin.cnr.it> wrote: >> > >> > only game point could be not enough.
