This tool simulates the adsorption of gas molecules unto metal organic frameworks (MOF) using Gibbs ensemble. The main difference between Gibbs adsorption and the adsorption using grand canonical ensemble (μVT) is that Gibbs adsorption uses two boxes for the simulation, the framework is contained in one box and the gas molecule is contained in the other box. The simulation computes the adsorption using the forcefield and not a fugacity coefficient or an equation of state. The volume of the gas box changes but the one for the framework remains constant. The MOFs used for the design of this tool include; IRMOF-1, and IRMOF-16. The gas molecules include; methane, argon, hydrogen, nitrogen, and carbon dioxide. The tool outputs the average absolute adsorption.
