<div dir="ltr">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.

(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 chris7 </div>
