Re: [QE-users] Dense k Point Interpolation to Arbitrary k Points for a Band Structure

Hi Lorenzo, Thanks for your reply. I just set lsym=.false. and no_overlap=.false. and ran bands.x again as you suggested. I'm waiting for the results now. Just in case it doesn't work, may I have more details on how to find out the intersection points by hand? In the output of the original band

Well, no, it's the same problem that was reported some time ago. Your lattice has a higher symmetry (tetragonal I) than triclinic (ibrav=14): ibrav = 7, celldm(1) = 16.22739617, celldm(3) = 0.6324556 corresponding to crystal axes (alat units) a(1) = ( 0.50 -0.5

Hello Truman, the bands code decides if bands cross or avoid using different criteria: per default symmetry, otherwise overlap of wfcs. You may getting a better result by changing criteria. Otherwise, you'll have to find the intersection point by hand, but if it incommensurate with the grid, it

Hi QE users, I'm using QE 6.7MaX. I plotted a band structure with the following k point coordinates. K_POINTS {crystal_b} 2 0.375 0.375 0.750 2000 !K 0.000 0.000 0.000 2000 !G I'd like to include specific k points in between K and G such that the expected band crossing at the red dot in

Yes, a fast file system. NFS via Ethernet may still be usable as long as you do not have heavy or frequent I/O. Writing via NFS is especially slow. For your information: https://gitlab.com/QEF/q-e/-/issues/299 Paolo On Mon, Mar 22, 2021 at 10:15 AM Takahiro Chiba < takahiro_ch...@eis.hokudai.ac.

Dear Jatin, it's very hard to tell what the problem is without additional details. Can you share your input? Can you try running without pool parallelism (to reduce the memory footprint)? Since you _may_ be hitting a code-related problem, you can also consider opening a confidential issue on

Dear Dr. Giannozzi, By the expression "parallel file system", you meant fast file systems such as LUSTRE, not NFS via ethernet, right? ---Sender--- Takahiro Chiba Undergraduate at Hokkaido University Expected graduation date: Mar. 2021 Expected to be a graduate student at HU from Apr. 2021 takahi
