Dear everyone, <div><br /></div><div>Nowadays I am trying to run a cluster geometry optimization by cp2k (spin polarization+DFTD3+multiplicity). For the 2 atoms cluster. I am wondering if my setting is reasonable or not, this is my first time using cp2k for spin polarization + DFTD3 + multiplicity. </div><div><br /></div><div>Thanks <br /><br />Yao</div><div><br /></div><div>I attached my input files:<br /></div><div><br /><b>mo.xyz</b><br /></div><div> 2<br /> <br />Mo 0.000000 0.000000 0.000000<br />Mo 0.000000 0.000000 1.700000<br /></div><div><br /></div><div><b>input.inp</b><br /></div><div><b><br /></b></div><div>&GLOBAL<br /> PROJECT momo<br /> RUN_TYPE GEO_OPT<br /> PRINT_LEVEL LOW<br />&END GLOBAL<br />&FORCE_EVAL<br /> METHOD QS<br /> &SUBSYS<br /> &CELL<br /> ABC 20.0 20.0 20.0<br /> PERIODIC NONE<br /> &END CELL<br /> &TOPOLOGY<br /> &CENTER_COORDINATES<br /> &END<br /> COORD_FILE_FORMAT XYZ<br /> COORD_FILE_NAME mo.xyz<br /> &END TOPOLOGY<br /> &KIND Mo<br /> BASIS_SET DZVP-MOLOPT-SR-GTH-q14<br /> POTENTIAL GTH-PBE-q14 <br /> &END KIND<br /> &END SUBSYS<br /> &DFT<br /> BASIS_SET_FILE_NAME /mnt/lustre/a2fs-work1/work/y07/shared/apps/core/cp2k/cp2k-2023.2/data/BASIS_MOLOPT<br /> POTENTIAL_FILE_NAME /mnt/lustre/a2fs-work1/work/y07/shared/apps/core/cp2k/cp2k-2023.2/data/GTH_POTENTIALS <br /> &QS<br /> EPS_DEFAULT 1.0E-12<br /> &END QS<br /> &MGRID<br /> CUTOFF 500<br /> NGRIDS 5<br /> REL_CUTOFF 60<br /> &END MGRID<br /> &SCF<br /> SCF_GUESS ATOMIC<br /> EPS_SCF 1.0E-05<br /> MAX_SCF 200<br /> &DIAGONALIZATION T<br /> ALGORITHM STANDARD<br /> &END DIAGONALIZATION<br /> &MIXING T<br /> METHOD BROYDEN_MIXING<br /> &END MIXING<br /> &END SCF<br /> &XC<br /> &XC_FUNCTIONAL PBE<br /> &END XC_FUNCTIONAL<br /> &vdW_POTENTIAL<br /> DISPERSION_FUNCTIONAL PAIR_POTENTIAL<br /> &PAIR_POTENTIAL<br /> TYPE DFTD3<br /> PARAMETER_FILE_NAME /mnt/lustre/a2fs-work1/work/y07/shared/apps/core/cp2k/cp2k-2023.2/data/dftd3.dat<br /> REFERENCE_FUNCTIONAL PBE<br /> &END PAIR_POTENTIAL<br /> &END vdW_POTENTIAL<br /> &END XC<br /> &END DFT<br />&END FORCE_EVAL<br />&MOTION<br /> &GEO_OPT<br /> TYPE MINIMIZATION<br /> MAX_DR 1.0E-03<br /> MAX_FORCE 1.0E-03<br /> RMS_DR 1.0E-03<br /> RMS_FORCE 1.0E-03<br /> MAX_ITER 200<br /> OPTIMIZER CG<br /> &CG<br /> MAX_STEEP_STEPS 0<br /> RESTART_LIMIT 9.0E-01<br /> &END CG<br /> &END GEO_OPT<br />&END MOTION<br /></div>
