<div dir="ltr"><div>Dear cp2k developers, Please help me. 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 This is my input: &GLOBAL PROJECT auxpothse_funco19 RUN_TYPE MD PRINT_LEVEL LOW FFTW_PLAN_TYPE PATIENT &END GLOBAL &FORCE_EVAL &DFT BASIS_SET_FILE_NAME BASIS_ALL POTENTIAL_FILE_NAME POTENTIAL UKS multiplicity 2 &MGRID CUTOFF 280 REL_CUTOFF 40 NGRIDS 5 &END &QS EPS_FILTER_MATRIX 1.0E-12 EPS_PGF_ORB 1.0E-12 &END &AUXILIARY_DENSITY_MATRIX_METHOD METHOD BASIS_PROJECTION ADMM_PURIFICATION_METHOD MO_DIAG &END &SCF SCF_GUESS ATOMIC # SCF_GUESS RESTART MAX_SCF 1000 EPS_SCF 1.0E-5 &OT MINIMIZER CG PRECONDITIONER FULL_ALL ENERGY_GAP 0.002 &END &OUTER_SCF EPS_SCF 1.0E-5 MAX_SCF 20 &END &END # &LOCALIZE # METHOD CRAZY # MAX_ITER 2000 # USE_HISTORY # &PRINT # &WANNIER_CENTERS # &EACH # MD 8 # &END # IONS+CENTERS # FILENAME =<a href="http://ohradikal-wannier.xyz" target="_blank" rel="nofollow">ohradikal-wannier.xyz</a> # &END # &END # &END &XC &XC_FUNCTIONAL &XWPBE SCALE_X -0.25 SCALE_X0 1.0 OMEGA 0.2 &END &PBE SCALE_X 0.0 SCALE_C 1.0 &END PBE &END XC_FUNCTIONAL &XC_GRID XC_DERIV NN10_SMOOTH XC_SMOOTH_RHO NN10 &END &HF &INTERACTION_POTENTIAL POTENTIAL_TYPE SHORTRANGE OMEGA 0.19 &END &SCREENING EPS_SCHWARZ 1.0E-10 &END FRACTION 0.25 &END &VDW_POTENTIAL DISPERSION_FUNCTIONAL PAIR_POTENTIAL &PAIR_POTENTIAL TYPE DFTD3 PARAMETER_FILE_NAME dftd3.dat REFERENCE_FUNCTIONAL PBE &END &END &END # &PRINT # &E_DENSITY_CUBE # &EACH # MD 8 # &END # FILENAME =Phenol-density.cube # APPEND # STRIDE 2 2 2 # &END # &END &END &SUBSYS &CELL ABC 9.988226 9.988226 9.988226 &END &COORD &END &KIND H BASIS_SET DZVP-MOLOPT-SR-GTH AUX_FIT_BASIS_SET cFIT3 POTENTIAL GTH-PBE-q1 &END # &KIND C # BASIS_SET DZVP-MOLOPT-SR-GTH # POTENTIAL GTH-B3LYP-q4 # &END &KIND O BASIS_SET DZVP-MOLOPT-SR-GTH AUX_FIT_BASIS_SET cFIT3 POTENTIAL GTH-PBE-q6 &END &END &END &MOTION &MD ENSEMBLE NVT STEPS 10000 TIMESTEP 0.5 &THERMOSTAT TYPE NOSE REGION MASSIVE &NOSE TIMECON 10 &END &END TEMPERATURE 370.15 &END &PRINT &RESTART &EACH MD 1 &END &END &END &END #&EXT_RESTART # RESTART_FILE_NAME -1.restart # RESTART_THERMOSTAT F #&END 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!
