Re: problem in convergence of phonon dispertion calculation

Hi! Did you check whether: 1] Your 1st dataset is well converged, 2] You use the same input parameters in RF calculation as in your relaxation calculation (ecut, ecutsm, dilatmx, ngkpt, shiftk, nshiftk,...), 3] Try putting npulayit to higher value that default (nnsclo and nline, also). Igor thank y...

Re: problem in convergence of phonon dispertion calculation

thank you Boris for your reply. I tried but it does not converge Hi again It may be a parallelisation issue. How many cpus are you using for the calculation ? Thanks to the symmetries, the number of kpts has been reduced to 48. If you use more than 48 cores, abinit will switch to band parallelisati...

a question in NLO

I have a question for the calculation of nonlinear optical coefficients by the DFPT method. we know that the nonlinear optic is the material response to laser radiation
can us considered the laser radiation as a perturbation.
and thanks in advance

Re: NLO+PAW

thank you for your reply yes I put nband = number of valence band I have another question for you I want to calculate the nonlinear optical coefficients and OE coefficients by applying the PDFT where I need all three perturbations (EF, stress and atomic displacement) but I read that it is not yet po...

thank you prof marc for the reply
i have use the latest version of the two code v2.3 for atompaw and v3.2 for atompaw2abinit
i will generated the atomic data for the iodine
if you want i send you the input file

Re: Installation

HI
here is the link where you can download the windows version for ABINIT
gunzip(decompress) the file, then you put your executables in systéme32 and you can run them through a DOS command
I advise you to use the Linux platform is more interesting
good luck
