Re: [QE-users] [External Email] Re: Error in Band structure calculation using hybrid functionals

2022-09-20 Thread Johnson, Miles R.
Thanks! It looks like it was a memory issue, the scf calculation never finished 
and the error message turned out to be in a different output file.

Do you have enough memory? Looks like a memory issue.

Hello Miles,

I've followed the same tutorial to obtain the band structure and DOS for SrTiO3 
using the HSE functional. I used QE-7.1 and open_grid.x worked for me, so I 
suppose the problem has to do with your input files.
What do they look like?

Best,
Simon
