ERROR kptopt=0 W90

Post by resu » Sun Jun 07, 2020 2:28 pm

Dear all,

I have a problem with the W90 interface. I want to generate UKN files for particular k-points, rather than for a grid of the BZ or along a path. For that, I set kptopt=0, but Abinit stops. I write the log, .out and .in file at the end of this message. Which is the reason of the error? How can generate the UKN files for these particular k-points?

LOG FILE

mlwfovlp: you should give k-point in the full brillouin zone
with explicit k-points (or kptopt=3) and istwfk 1

** mlwfovlp_setup: call wannier90 library subroutine wannier_setup
Non-symmetric k-point neighbours!
Error: examine the output/error file for details

in FILE
