castep模块计算问题
在castep文件中显示如下,
BFGS: Warning - looks like this system is as converged as possible.
Maybe your geometry convergence tolerances are too tight?
BFGS: finished iteration 102 with enthalpy= -2.33848980E+003 eV

BFGS : Geometry optimization completed successfully.
但在job explorer则显示"the job has failed".这是怎么回事,在castep有警告:“There were at least 13 warnings during this run ***
*** => please check the whole of this file carefully! ” ,但怎么着错误原因。刚开始利用这个优化的结构继续计算性质,在job explorer中仍显示failed的错误信息,而且选了pdos的计算,但分析时却选不了partial选项,不能画PDOS图。
希望高手指点一二。 返回小木虫查看更多
把结构发上来看看scf过不去可能是精度不充分、自旋初始值不合理、或是代数方法采用的不太好、初始结构偏离平衡结构太多等造成,降低精度不见得会有好的情况

近期问题太多,周围的人都没碰到。真不知该怎么解决。
