问题二:石墨烯体系2的能带计算出现了不一样的问题,请教诸位应该如何处理,其OUTCAR显示:
maximum and minimum number of plane-waves per node : 176429 176169
maximum number of plane-waves: 176429
maximum index in each direction:
IXMAX= 44 IYMAX= 17 IZMAX= 55
IXMIN= -44 IYMIN= -17 IZMIN= -55
WARNING: aliasing errors must be expected set NGX to 178 to avoid them
WARNING: aliasing errors must be expected set NGY to 70 to avoid them
WARNING: aliasing errors must be expected set NGZ to 222 to avoid them
aliasing errors are usually negligible using standard VASP settings
and one can safely disregard these warnings
serial 3D FFT for wavefunctions
parallel 3D FFT for charge:
minimum data exchange during FFTs selected (reduces bandwidth)
