Hi Gyanu
I set 'nosym=.false.' in my nscf.in, Then you encounter the following error:
Error in routine epw_setup (1):
coarse k-mesh needs to be strictly positive in 1st BZ

Re: forrtl: severe (174): SIGSEGV, segmentation fault occurred
Hi Roxana
I followed your advice and changed to the latest version of epw.x5.7 for recalculation. Unfortunately, the error still exists.
setting 'calculation = scf' is my input error, but in the calculation process was setting 'calculation=nscf'

Hi H.Lee
The wout file has a total of 82691 lines. I put the file in the compressed package, please have a look

Re: Issues running epw.x to calculate the electro-phonon coupling
Hi H. Lee
Thanks for you reply
So I need to modify the scf.in file in phonons and set noncolin=.true., lspinorb=.true. and starting_magnetization=0. And then redo the phonon calculation?

Re: Issues running epw.x to calculate the electro-phonon coupling
Hi Gyanu Thanks for your reply. I followed your advice and carefully checked scf.in in phonons and EPW files. There is a problem with not using the same scf.in. and the source of the error is probably in the scf.in inside phonons. I typed noncolin=.true. and lspinorb=.true. These two parameters are ...

Hi H. Lee I have checked ph.out file and prefix.dyn file, and found a problem that could lead to error reporting, but I am not clear that it is just not the problem that leads to error reporting. I hope you can help me check it. ph.out Program PHONON v.6.7MaX starts on 16Jan2023 at 19:17:40 This pro...
