vasp计算未报错却直接停止。【设置EDIFF=1E5, EDIFFG=-0.05】(如图1)感觉不像算完的样子,烦请各位指导一下,感激不尽。
OUTCAR的最后几行如图2所示;
INCAR具体如下
ISTART = 0 (Read existing wavefunction; if there)
ISPIN = 2 (Spin polarised DFT)
ICHARG = 2 (Non-self-consistent: GGA/LDA band structures)
LREAL = Auto (Projection operators: automatic)
ENCUT = 500 (Cut-off energy for plane wave basis set, in eV)
PREC = A (Precision level)
LWAVE = .T. (Write WAVECAR or not)
LCHARG = .T. (Write CHGCAR or not)
ADDGRID= .TRUE. (Increase grid; helps GGA convergence)
# LVTOT = .TRUE. (Write total electrostatic potential into LOCPOT or not)
# LVHAR = .TRUE. (Write ionic + Hartree electrostatic potential into LOCPOT or not)
# NELECT = (No. of electrons: charged cells; be careful)
# LPLANE = .TRUE. (Real space distribution; supercells)
NPAR = 4 (Max is no. nodes; don't set for hybrids)
#NCORE = 4
# NWRITE = 2 (Medium-level output)
# KPAR = 2 (Divides k-grid into separate groups)
# NGX = 500 (FFT grid mesh density for nice charge/potential plots)
# NGY = 500 (FFT grid mesh density for nice charge/potential plots)
# NGZ = 500 (FFT grid mesh density for nice charge/potential plots)
ISIF = 3 (Stress/relaxation: 2-Ions, 3-Shape/Ions/V, 4-Shape/Ions)
Electronic Relaxation
ISMEAR = 0 (Gaussian smearing; metals:1)
SIGMA = 0.05 (Smearing value in eV; metals:0.2)
NELM = 150 (Max electronic SCF steps)
#NELMIN = 6 (Min electronic SCF steps)
EDIFF = 1E-05 (SCF energy convergence; in eV)
# GGA = PS (PBEsol exchange-correlation)
Ionic Relaxation
NSW = 150 (Max electronic SCF steps)
IBRION = 2 (Algorithm: 0-MD; 1-Quasi-New; 2-CG)
#POTIM = 0.1
#ISIF = 2 (Stress/relaxation: 2-Ions, 3-Shape/Ions/V, 4-Shape/Ions)
EDIFFG = -0.05 (Ionic convergence; eV/AA)
# ISM = 2 (Symmetry: 0=none; 2=GGA; 3=hybrids)
ALGO = N
#IVDW = 11
#LMAXMIX = 4
DFT+U Calculation
LDAU = .TRUE. (Activate DFT+U)
LDATYPE= 2 (Dudarev; only U-J matters)
LDAUL = -1 2 -1 (Orbitals for each species)
LDAUU = 0 4.7 0 (U for each species)
LDAUJ = 0 0 0 (J for each species)
LMAXMIX= 4 (Mixing cut-off; 4-d, 6-f)
