GGA+ U計(jì)算問題
|
|
做ZnO納米線加U 參數(shù)設(shè)置:交換關(guān)聯(lián)函數(shù)是GGA-PW91,K點(diǎn)布里淵區(qū)為:1×1×8,截?cái)嗄転?00eV,構(gòu)選上 spin polarized, use LDA+U ,收斂精度為:Coarse,energy為1.0×10-4eV,作用在原子上的最大力為0. 2eV/Å,最大應(yīng)力為0.4 GPa 一直出現(xiàn)不收斂的問題,希望高手幫忙啊,特別急,已經(jīng)好久了這個(gè)問題一直沒解決,請(qǐng)問做加U計(jì)算時(shí)參數(shù)設(shè)置要注意些什么? 具體問題如下: *Warning* max. SCF cycles performed but system has not reached the groundstate. Current total energy, E = -739215.8533861 eV Current free energy (E-TS) = -739215.8533861 eV (energies not corrected for finite basis set) NB est. 0K energy (E-0.5TS) = -739215.8533861 eV ******************************************************** Warning: electronic minimisation did not converge during finite basis set correction. ******************************************************** Checkpoint file cannot be written. Error calculate_finite_basis : Convergence failed when doing finite basis set correction. Current trace stack: calculate_finite_basis_corr check_elec_ground_state castep Error calculate_finite_basis : Convergence failed when doing finite basis set correction. Current trace stack: calculate_finite_basis_corr check_elec_ground_state |
