[QE-users] Using SCAN functionals with QE 7.2

[Fabrizio Ferrari Ruffino]

Hello,
are you using dftd3? If so, which dftd3_version (input file)?
Only some selected functionals are allowed with dftd3, scan is usable with version 4 only.

Cheers,
Fabrizio

Subject: [QE-users] Using SCAN functionals with QE 7.2


Hello,



I am trying to use the SCAN functional with QE 7.2 and libxc 5.2.3. I have found some older threads about what value to assign to input_dft, but all the following have failed so far:



“scan”

“r2scan”

“rvv10-scan”

“XC-000i-000i-000i-000i-263L-292L“

“XC-001i-004i-013i-vdw2”



The code stops and prints the error message:

“””

program stopped due to: functional name unknown

STOP must stop!

“””



Could you provide me any guidance on how to overcome this? Is this an issue with the libxc version?



Kind regards,

Pedro Melo
