unknown error after wannierization job

[plasmon]

Dear Developers,

Recently I met a problem when using EPW to study 2D materials. I have finished scf-ph-q2r-nscf, and some unknown error takes place after w90. I have attached the in and out files here.Could you please tell me how to fix this problem? Thank you very much!

Best,
Hao Zhang

Hi Hao,

Can you make sure "dvscf_dir = './save' " contains all the required files? They are prefix.dyn_qXX, prefix.dvscf_qXX, and patterns.XX.xml in prefix.phsave directory.

Best,
Hari Paudyal

Dear Hao Zhang:

Since you are using EPW v5.3, you should not use nosym=.true. in nscf.in.
Please read carefully the Releases page at https://docs.epw-code.org/doc/Releases.html .
Additionally, your k and q grids are not commensurate. Please modify the number of grids.

Lastly, although it is not related to your error, please read the post about 2D materials in EPW at viewtopic.php?f=3&t=1311

Sincerely,
