小弟我用VASP進行aimd計算，NPT系綜，設(shè)定600K，始終無法達到設(shè)定測試，相差200K左右。懇求各位大牛指點一二，跪謝！！ 以下為INCAR文件： ##############################Global Parameters############################### SYSTEM = aimd ISTART = 0 # (Read existing wavefunction; if there) ICHARG = 2 LREAL = Auto # (Projection operators: automatic) ENCUT = 390 # (Cut-off energy for plane wave basis set, in eV) PREC = Normal # Accurate # (Precision level) #SYMPREC = 1.0E-6 ISYM = -1 LWAVE = .F. # (Write WAVECAR or not) LCHARG = .F. # (Write CHGCAR or not) #############################Electronic Relaxation############################# ISMEAR = 0 # (Gaussian smearing; metals:1) SIGMA = 0.1 # (Smearing value in eV; metals:0.2) NELM = 100 # (Max electronic SCF steps) NELMIN = 5 # (Min electronic SCF steps) EDIFF = 1.0E-4 # (SCF energy convergence; in eV) IVDW = 12 ############################Ionic Relaxation######################################## IBRION = 0 # (Algorithm: 0-MD; 1-Quasi-New; 2-CG) POTIM = 1 # (分子動力學步長，一般為1 fs) NSW = 500 # (設(shè)置動力學步數(shù)) TEBEG = 600 # (設(shè)置初始溫度) #TEEND = 600 # (設(shè)置結(jié)束溫度) PSTRESS = 0 MDALGO = 3 # (1 for Andersen, 2 for Nose-Hoover, 3 for Langevin, et al.) #ANDERSEN_PROB = 1 ISIF = 3 # (Stress/relaxation: 2-Ions, 3-Shape/Ions/V, 4-Shape/Ions) EDIFFG = -0.02 # (Ionic convergence; eV/AA) ############################附加關(guān)鍵詞######################################## NBLOCK = 1 # After NBLOCK ionic steps the pair-correlation function and the DOS are calculated and the ionic configuration is written to the XDATCAR-file KBLOCK = 20 # After KBLOCK*NBLOCK ionic steps the averaged pair-correlation function and DOS are written to the files PCDAT and DOSCAR.
