| Abstract: | Numerical modeling of nano/micro devices needs measurement of thermo-fluid properties in molecular simulations. Therefore, special attention has been paid to the method of numerical measurement of fluid properties. Details about pressure calculation in a molecular system and its sensitivity to approximations made are studied in this paper. Convergence behavior of kinetic and potential parts of pressure and the effect of cut-off distance on pressure calculation in different bin sizes are studied. Finally a method is introduced for the correct calculation of pressure. This method is based on the assumption that macroscopic properties should be independent from the bin sizes. |
