摻雜后的結(jié)構(gòu)計(jì)算彈性常數(shù)出現(xiàn)問題(急),請大家一定要幫幫忙啊~~

我有兩個(gè)問題,想問一下大家, 1.我在計(jì)算彈性常數(shù)的時(shí)候計(jì)算出來的cij-1-2.castep這種文件中都是收斂的,但老是出現(xiàn)這樣的提醒 ,這是怎么回事。 *** There were at least 4 warnings during this run *** *** => please check the whole of this file carefully! *** 2.如果cij-1-2.castep這類文件中不收斂,是怎么回事,是不是要重新計(jì)算。 |

BFGS: Warning - trial step suggests complex energy landscape in which simple line minimization will fail. - This is usually an indication that the forces/streses are not accurate enough. Consider making the following changes: 1) Increase cutoff_energy or basis_precision 2) Reduce elec_energy_tol and/or elec_force_tol 3) Increase grid_scale 4) Increase fine_grid_scale - Proceeding with a bisection search to find root instead. BFGS: Warning - Repeated consecutive reset of inverse Hessian BFGS: without satisfying convergence criteria which BFGS: looks like BFGS has run out of search directions. BFGS: Warning - Lets try allowing some uphill steps and see if BFGS: we can get around this barrier. BFGS: Warning - It is possible that the system may now converge to BFGS: a stationary point OTHER than the desired minimum. BFGS: Hint - this may be an indication that either: BFGS: a) you are using a poor guess at geom_frequency_est BFGS: and/or geom_modulus_est, or BFGS: b) you are using unrealistic convergence criteria. BFGS: Suggest therefore that you consider changing them! 總是出現(xiàn)這樣的警告,這是什么意思,怎么解決 |
