Thank you for the advice, I was using an older version of the code (6.2.1). I don't receive the same error when running with Quantum ESPRESSO 6.7, so whatever was wrong must have been fixed. From, John Stoppelman > On 06/08/2021 9:32 AM Paolo Giannozzi wrote: > > > If the st

If the structure is correct and pseudopotentials reasonably good, there isn't much that can be done. You may want to use "ParO" or "PPCG" diagonalization instead of "cg" that is very slow. Paolo On Mon, Jun 7, 2021 at 6:44 PM John Stoppelman wrote: > Hello, > I am running a vc-relax calculation

[QE-users] S Matrix not positive definite error with PBEsol

2021-06-07 Thread John Stoppelman
Hello, I am running a vc-relax calculation for a crystal structure, and I'm trying to compare the results between PBE and PBEsol. The SCF converges with PBE using the default Davidson diagonalization. When I switch to PBEsol pseudopotentials from the PSlibary, I receive the error: Error in rou
