stop at "Using .ukk from disk"
Posted: Mon Jun 17, 2019 1:25 am
Hello Everyone,
I am a beginner of epw. A few days ago I tried the exercise1 in Wed.4. (http://epw.org.uk/School2018/School2018 ... .Verdi.pdf), and it ran successfully.
However, when I changed the calculated material from Pb to 2D-As, the calculation stopped at the last step. In the epw4.out file, the last content is "Using As.ukk from disk".
My input files:
scf.in
ph.in
nscf.in
epw.in
epw2.in
epw3.in
epw4.in
and the last of epw4.out looks like
Can anybody tell me how to change the input files to make the calculations go smoothly.
Looking forward for the replies.
Best wishes
Yue Gu
