【求助】dmol3中max.displacement不收敛已有1人参与

|
我用α氧化铝2*2超胞，001表面，六原子层，下三层固定，上面三层驰豫，同样的方法，第一层与第二层s12与文献值，很接近，s23差别较大，优化后与Ni团簇一起作用，结构优化，怎么都不收敛，即使用coarse，smearing 0.1，仍然不收敛，这是input和outmol结果。可能是构型不合理，我就又从头做了一遍，仍然这样。 # Task parameters Calculate optimize Opt_energy_convergence 1.0000e-004 Opt_gradient_convergence 2.0000e-002 A Opt_displacement_convergence 5.0000e-002 A Opt_iterations 1000 Opt_max_displacement 0.3000 A # Cartesian constraints Opt_fixed 4 XYZ 5 XYZ 6 XYZ 7 XYZ 8 XYZ 14 XYZ 15 XYZ 16 XYZ 17 XYZ 18 XYZ 24 XYZ 25 XYZ 26 XYZ 27 XYZ 28 XYZ 34 XYZ 35 XYZ 36 XYZ 37 XYZ 38 XYZ Symmetry off Max_memory 6044 # Electronic parameters Spin_polarization unrestricted Charge 0 Basis dn basis_version basfile_v4.4 Pseudopotential dspp Functional rpbe Aux_density octupole Integration_grid coarse Occupation thermal 0.1000 Cutoff_Global 3.5000 angstrom Scf_density_convergence 1.0000e-004 Scf_charge_mixing 0.2000 Scf_spin_mixing 0.5000 Scf_iterations 1000 Scf_diis 6 pulay # Kpoint definition file (intervals/offset): Kpoints file 2 2 1 0.0000 0.0000 0.0000 1bond.kpoints # Calculated properties |
