[Wien] scan xc functional

2018-06-28 Thread sandeep arora
Dear wien2k users I want to use scan exchange correlation for optimization of binary semiconductors(GaP).But the lattice constant varies with Rkmax at third decimal place even on increasing rkmax up to 11 and increasing ifft enhancement factor up to 4 in case.in0.although the E-V graph is smooth

At least on our SLURM system, mpirun is not supported and you have to use srun instead. In siteconfig, there is even an option "ifort + slurm"; why not trying to use these defaults ? Am 29.06.2018 um 00:23 schrieb venkatesh chandragiri: Dear Wien2k users, I have forwarded the suggestions give

After you click the "Calculate density with XCrysden" button, 1) the "Requires X-Windows system ... Calc" message appears immediately or 2) does the XCrySDen program open, the "Choose 2D/3D Density Plot" window appears (like that shown at http://www.xcrysden.org/doc/wien.html#__toc__6 ), then t

You will need to talk more to your sysadmin (maybe show this email). The simple one is the line *31 mpirun: Command not found.* This means what it says -- mpirun is not in your PATH and/or some other command is needed. This is being set in $WIENROOT/mpirun. The other one *32 setrlimit(): WARNING

Dear Wien2k users, I have forwarded the suggestions given by Prof. Gavin as well as Prof. Marks to the cluster administrator and now it seems that those earlier errors was rectified. However, there are still more errors coming out when I am submitting my job into SLURM based queuing process and st

v5,v5c,v5x are at z=0.5. v5 (1st number) is the total potential, v5c is the Coulomb and v5x is the exchange. (For a good calculation v5x should be small, it will never be zero.) Whether one should use v5 or v5c is something I have debated with myself. I suspect that there are enough uncertainties

Dear Prof. Gavin Abo Thank you very much. Yes it worked and I could finish one scf calculation with spin polarization. I have one more question. I know that, WF= VZERO -FERMI. Since I have given the vacuum along z-direction I believe I need z-component of Vzero . I found the values below from s

[Wien] Xcrysden works for structure view, not for electron density display

Dear all, Xcrysden works fine from the w2web interface (run locally), when viewing a structure. So, I think it is correctly installed and configured. However, it displays "requires X-Windows system ... Calc" when trying to use the "Calculate density with Xcrysden" button, or "requires X-Windo
