【求助】已经修改过很多遍,但是算完后表面结构完全扭曲了,请大家看看错误到底在哪里

非常感谢,我把下面的三层原子固定了,最后还要解开继续优化一遍吗? kgrid_cutoff 0.0 Bohr 没有设置kgrid_Monkhorst_pack。只计算gamma点。 NumberOfAtoms 51 NumberOfSpecies 5 %block ChemicalSpeciesLabel 1 79 Au 2 1 H 3 6 C 4 7 N 5 8 O %endblock ChemicalSpeciesLabel PAO.BasisType split PAO.BasisSize DZP PAO.EnergyShift 200 meV LatticeConstant 8.6514 Ang %block Latticeparameters 1 1 3.128 90. 90. 120. %endblock AtomicCoordinatesFormat Ang # Default value: NotScaledCartesianBohr # * Bohr or NotScaledCartesianBohr # * Ang or NotScaledCartesianAng # * ScaledCartesian # * Fractional or ScaledByLatticeVectors %block AtomicCoordinatesAndAtomicSpecies 0.003996234 -0.002307227 0.999989353 1 0.003996234 -0.002307227 8.063812162 1 1.445893027 0.830172274 5.709204559 1 0.003996234 1.662651776 3.354596956 1 2.887789820 -0.002307227 0.999989353 1 2.887789820 -0.002307227 8.063812162 1 4.329686613 0.830172274 5.709204559 1 2.887789820 1.662651776 3.354596956 1 5.771583406 -0.002307227 0.999989353 1 5.771583406 -0.002307227 8.063812162 1 7.213480199 0.830172274 5.709204559 1 5.771583406 1.662651776 3.354596956 1 -1.437900558 2.495131277 0.999989353 1 -1.437900558 2.495131277 8.063812162 1 0.003996234 3.327610779 5.709204559 1 -1.437900558 4.160090280 3.354596956 1 1.445893027 2.495131277 0.999989353 1 1.445893027 2.495131277 8.063812162 1 2.887789820 3.327610779 5.709204559 1 1.445893027 4.160090280 3.354596956 1 4.329686613 2.495131277 0.999989353 1 4.329686613 2.495131277 8.063812162 1 5.771583406 3.327610779 5.709204559 1 4.329686613 4.160090280 3.354596956 1 -2.879797351 4.992569782 0.999989353 1 -2.879797351 4.992569782 8.063812162 1 -1.437900558 5.825049283 5.709204559 1 -2.879797351 6.657528785 3.354596956 1 0.003996234 4.992569782 0.999989353 1 0.003996234 4.992569782 8.063812162 1 1.445893027 5.825049283 5.709204559 1 0.003996234 6.657528785 3.354596956 1 2.887789820 4.992569782 0.999989353 1 2.887789820 4.992569782 8.063812162 1 4.329686613 5.825049283 5.709204559 1 2.887789820 6.657528785 3.354596956 1 6.863709387 -2.478773934 14.378322217 3 5.668403242 -2.531756860 15.098161834 3 6.840822784 -2.522024426 12.982851457 3 7.770774051 -2.480803597 12.422813565 2 4.450208749 -2.627990414 14.422529723 3 5.622628292 -2.618257980 12.307219345 3 3.520257482 -2.669211244 14.982567615 2 4.427322146 -2.671240905 13.027058962 3 3.479564859 -2.746110766 12.501416086 2 7.811466674 -2.403904073 14.903965093 2 5.597387816 -2.665958556 10.768165229 4 5.578320785 -2.701992284 9.605540764 3 5.692496422 -2.486224492 16.567258945 4 5.469941897 -1.404116075 17.109479974 5 5.933793082 -3.532913187 17.167851556 5 %endblock AtomicCoordinatesAndAtomicSpecies %block GeometryConstraints Position 1 position from 3 to 5 position from 5 to 9 position from 11 to 13 position from 15 to 17 position from 19 to 21 position from 23 to 25 position from 27 to 29 position from 31 to 33 position from 35 to 36 %endblock GeometryConstraints OptialCalculation .true.
