I want to calculate total stress in Y direction for a system (Syy). for this reason I use following command in my input script :
compute 2 all stress/atom
compute 4 all sum c_2
But I don’t know , how can obtain the stress (Pa units) from the output stress of these commands.
I think ,it must be divided by initial volume of system but i amn’t sure.
