I am simulating 2 dimensional MD in LJ units. So, the “stress per atom” has the unit of (pressure* area) according the manual.So, in order to present the pressure value in pressure unit like Pa,Bar and … in my results first I should divide it per model or region SURFACE and then multiply its value to epsilon/sigma^3??
Actually, I think that I should multiply to epsilon/sigma^2 instead of epsilon/sigma^3. but the resulted value became too small and I am not sure about that.
any help is highly appreciated
