Hello everybody,
I am trying to perform an AIMD-calculation with the HSE-functional.
I get the following warning:
*** 15:27:23 WARNING in hfx_types:hfx_create_neighbor_cells :: Periodic ***
*** Hartree Fock calculation requested with use of a truncated or ***
*** shortrange potential. The cutoff radius is larger than half the ***
*** minimal cell dimension. This may lead to unphysical total energies. ***
*** Reduce the cutoff radius in order to avoid possible problems. ***
*** hfx_types.F line 1448

I tried also to vary the cutoff-radii in the SE-Section: There are the
following subsections in which you can define the cutoff-radius:
COULOMB, EXCHANGE, SCREENING, LR_CORRECTION. (I tried it also with very
small cutoff-radii)
Nothing helps!
Does anyone has another idea or knows this problem?
Maybe I forgot one keyword which defines the cutoff-radius?
I need to take the HSE06 functional because I need the screened exchange in
combination with the MIC in order to calculate my system as a condensed
phase.
Thank you!
Best regards
