I have been using “fix indent” command in my work. I have a doubt regarding the meaning of f_ID[N] command for getting the vector forces calculated by fix.
Like if I use command:
thermo_style custom step temp pe ke f_6 f_6 f_6
then how do I differentiate vector force components for x, y and z directions on this basis? Do the numerals in “” show any direction vectors ?
Please do guide regarding the same.
