[求助] 怎样输出应力值

大家好,我是在LAPPMS运行后出来的dump导入到VMD中的,请问下,在dump文件中怎么可以输出每个原子的应力值啊,我用了
compute              new3  all stress/atom语句计算每个原子的应力
.......
dump                   1 all custom 100 dump.LSP tag x y z vx vy vz c_new3输出原子的坐标,速度,应力,,为什么Lammps分析的时候老是说无效的dump命令呢

I think you need to read the manual  very very very carefully.
here it is :http://lammps.sandia.gov/doc/dump.html
and check your command very carefully !
at last I have a question :  What's the damnable  "tag" mean in your command?

and best wishes !

我仔细看了手册了啊,改成了
dump 1 all custom 100 dump.LSP id type xs ys zs id type c_new3
可是到最后还是Errorump custom computr does not calculate per-atom vector为什么老是说每个原子的分量没有被计算啊?我用了compute命令的啊

in my opinion, you need to read them more carefully, and check your command again, if the "dump " doesn't wrok, there must be something wrong with your command.
maybe your Variable  "c_new3"  is not properly defined.
if you want to output the force of each atom, why don't you use :fx,fy,fz
