An important feature of the DCVMD setup is that the system begins without any gas molecules. As the simulation progresses, the exchange moves with the reference bulk system introduce gas into the source control volume, leading to a flux in the system and ultimately a steady state condition. It is crucial that data collection and analysis commence only after the system has reached steady state to ensure that the results are statistically valid. demonstrate that gas molecules initially enter the system from the inlet side, leading to the gradual formation of a concentration gradient. Over time, the gas concentration increases throughout the system until steady state is reached, with a clear concentration gradient from inlet to outlet. Based on these observations, the system reliably achieves steady state before the 200 ns mark in the NE-DCVMD simulations. Consequently, all subsequent analyses and calculations are based on data collected after the first 200 ns of the simulation.
