Dear Users and Developers,
In a Metallic model (Unit=METAL), I have a wall (command “fix rigid group”).
I applied command “addforce…NULL NULL zforce” to the group to generate external pressure.
I need measure the external pressure in SI UNIT.
Based on pressure definition (P=F/A) I calculate the external pressure something like this:
zforce(eV/A) * atom counts / area(A^2)=pressure (eV/A^3)= pressure (Gpa)/160.2
area =lx*ly (Ang.^2)
But the pressure unit in METAL is bar=10^5 Pa
Is my calculation correct? Or may be it needs a correction factor?
