[QE-users] Error in Band structure calculation using hybrid functionals

[Johnson, Miles R.]

Hello all,

I am trying to follow this tutorial: https://christoph-wolf.at/2018/10/10/band-structure-calculations-in-qe-using-hybrid-functionals/
in order to perform a band structure calculation using a hybrid functional (hse). When I run the first scf calculation, it ends as shown in one of the pictures below, saying the calculation converged but then having some kind of "Bad Termination"; notably, it does not say it wrote all output data to the .save file as it usually does.

When I try to run open_grid.x as the next step specified in the tutorial, I get an error as shown in the second picture, as though a file is missing.

Some comments on the tutorial seem to be having the same issue, and the only suggested solution is to use an older version of QE. Perhaps the tutorial is just out of date for some reason - does anyone here know how to calculate a band structure and/or density of states with hybrid functionals?

Thanks,
Miles

In recent years the interest in hybrid functionals (that is the incorporation of parts of Hartree-Fock exchange in calculations based on common approximations of exchange-correlations such as LDA, GGA and so on) has steadily increased owing to its improvement over most common functionals, especially when it comes to band-gap calculation of extended solids - see…
