vaspkit201算弹性常数的疑问
算的是单斜的Ag2S,我把优化好的POSCAR放进来,vaspkit201前处理想得到应变文件夹,却报错说我的结构是三斜晶系算不了,但我的POSCAR是单斜呀,后面我还把那些很接近0的那些晶格常数手动改为0,还是一样的效果,下面是我的POSCAR和VPKIT.in POSCARPOSCAR file written by OVITO Basic 3.7.4

所以想问一下,是我哪里打开方式错了吗 本帖最后由 phx567 于 2022-7-17 17:28 编辑
这个是报错的信息,提示Error! Calculated elastic constants for Triclinic Systems are still problematic
