Hello, I am observing nucleation and growth of bubbles in a solution of methane in water with methane present at various levels of supersaturation. The system consists of a total 0f 2000 molecules in a cubic box with the number of CH4 varying from 80 to 200. I am using a single point Lennard

Hi Sujith, you can try to translate the initial configuration by, say, L/2 in all directions using trjconv. If the bubble appears again at the edge, I would suspect artifacts. If you are using Verlet cutoff scheme, you can also try to change it to group - it helped in my simulation when a droplet

Hi, If your box is periodic then there are no edges or faces... Also note that if you mentally divide your box in e.g. three parts in each dimension, the 27 resulting cubes have 26 that are near an original edge or face, so of course things will look like they happen near edges and faces... Mark
