[QE-users] Convergence with interstitials

2021-01-08 Thread Tejas Ramakrishnan
Hello everyone, To study diffusion barrier using NEB, to prepare the initial and final states, I am performing "relax" calculations with interstitials inserted into a vc-relaxed pure bcc W cell structure. I have used k-points, cut-offs and cells size after verifying the convergence, but with

Dear Paolo, Thank you, this is what Lorenzo Paulatto suggested, too: the dynmat.x (not matdyn.x) code computes the IR cross section, if you give it in input the dynamical matrix at Gamma with effective charges. In recent versions of the code, the calculation is done in LR_Modules/dynmat_sub.f90,

Try to disable parallel diagonalization with run-time option "-nd 1": the default has changed between 6.4.1 and 6.7. It is impossible to say anything more without knowing how you run your codes. > ./configure --prefix=/THL7/home/soft/QuantumEspresso/qe-6.7 > --with-scalapack=intel CC="icc"

[QE-users] error in QE6.7: too many communicators

2021-01-08 Thread jqhuang16b
Dear QE users and developers, I have been using QE6.4.1 version quite normally. Few days ago, I tried to compile the latest QE6.7 with the same Intel compiler. The compilation went smoothly, but there were two issues in the calculation. First, the calculation of QE6.7 seems much slower than

The dipole induced by a phonon can be computed from phonon displacements and effective charges: see variable "polar", computed in routine RamanIR, file LR_Modules/dynmat_sub.f90, called by PHonon/PH/dynmat.f90 Paolo On Thu, Jan 7, 2021 at 10:58 PM Michal Krompiec wrote: > Hello, > > In
