help ! forrtl: severe (174): SIGSEGV, segmentation fault occurred

Post by shamlg123 »

Dear developer:
Last time wen I posted my error, and I delete the line "elph = .true." then the coe can run .
but new error comes as "forrtl: severe (174): SIGSEGV, segmentation fault occurred"
Now I post the ph.in, nscf.in & epw.in as below. Can you help me fix the issues ?
(nscf.out & epw.out)
Thank you very much !
Michael Kong
PS:
1.The example of MgB2 can run successfully witout any problem.
2. My QE version is 7.0

Re: help ! forrtl: severe (174): SIGSEGV, segmentation fault occurred

Dear Michael Kong:

(from your nscf.in)
...
ibrav = 12
lda_plus_u = .TRUE.
nat = 4
nspin = 2
ntyp = 3
...
EPW is not compatible with nspin=2. Also it doesn't work with LDA+U.

Sincerely,

H. Lee
