请教大佬,算AB-A-B的二次差分电荷密度,A和B用的是AB晶格优化之后删掉另外一部分得到的晶格,所以说,三者的晶格参数是一样的,我在静态计算的时候,INCAR中没有设NGX这一系列的参数。
问题是我在用Veata做二次差分电荷密度的时候,还是出现错误提示:“Number of data grids in the 3D data sets do not match each other”
贴两张图,请大伙看看,是什么问题? K点都是:
KPT-Resolved Value to Generate K-Mesh: 0.020
0
Gamma
9 23 1
0.0 0.0 0.0
一张是三者的晶格参数,
一张是Vesta作图时,在进行减去A或B晶格参数时的错误提示。
AB的 OUTCAR :
dimension x,y,z NGX = 90 NGY = 36 NGZ = 180
dimension x,y,z NGXF= 180 NGYF= 72 NGZF= 360
support grid NGXF= 360 NGYF= 144 NGZF= 720
A的 OUTCAR :
dimension x,y,z NGX = 70 NGY = 28 NGZ = 140
dimension x,y,z NGXF= 140 NGYF= 56 NGZF= 280
support grid NGXF= 280 NGYF= 112 NGZF= 560
AB晶格和A 静态时的INCAR如下:
AB晶格静态时的INCAR :
Global Parameters
ISTART = 1 (Read existing wavefunction; if there)
ISPIN = 1 (Non-Spin polarised DFT)
# ICHARG = 11 (Non-self-consistent: GGA/LDA band structures)
LREAL = .FALSE. (Projection operators: automatic)
# ENCUT = 400 (Cut-off energy for plane wave basis set, in eV)
PREC = Normal (Precision level)
LWAVE = .TRUE. (Write WAVECAR or not)
LCHARG = .TRUE. (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)
# 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)
Static Calculation
ISMEAR = 0 (gaussian smearing method)
SIGMA = 0.05 (please check the width of the smearing)
LORBIT = 11 (PAW radii for projected DOS)
NEDOS = 2001 (DOSCAR points)
NELM = 60 (Max electronic SCF steps)
EDIFF = 1E-08 (SCF energy convergence; in eV)
