关于使用siesta计算ordern的参数设置和问题解决 已有1人参与

siesta新手想试一下做ordern的计算，修改参数成 SolutionMethod=ordern后，计算了TiN体系的能量。返回了这样的错误。求大神指导！！需要设置其他的参数吗？ordern计算需要注意什么问题呢。手册上有句话是说ordern subsystem is quite fragile and only works for systems with clearly separated occupied and empty states. Note also that the option to compute the potential automatically does not yet work in parallel. 下面是返回的错误提示。 Cannot do O(N) with k-points. Stopping Program from Node: 3 Cannot do O(N) with k-points. Stopping Program from Node: 3 Cannot do O(N) with k-points. Stopping Program from Node: 2 Cannot do O(N) with k-points.

请问如何修改呢？把Kgridcutoff改成1就行吗？听导师说可能单胞太小了。但我看看官方给出的例子有一个计算H2O ordern的，那个原子数也少。还有kridcutoff和kgridMonkhorstpack 有什么不一样 ？请高人指教。下面附上H20 ORDERN 的例子fdf文件。这个可以算出来。 SystemName Water molecule, using order-N method SystemLabel h2o NumberOfAtoms 3 NumberOfSpecies 2 %block ChemicalSpeciesLabel 1 8 O # Species index, atomic number, species label 2 1 H %endblock ChemicalSpeciesLabel AtomicCoordinatesFormat Ang %block AtomicCoordinatesAndAtomicSpecies 0.000 0.000 0.000 1 0.757 0.586 0.000 2 -0.757 0.586 0.000 2 %endblock AtomicCoordinatesAndAtomicSpecies SolutionMethod ordern |
