The model allows defining a rectangular enclosure and an arbitrary number of walls and argon atoms. The model simulates ideal gases and an interaction with the walls by diffuse reflection or real gases with both the wall interaction and the Lennard-Jones inter-atomic potential.
During the simulation, the temperature setpoint of all walls, including the enclosure, is adjusted with the mouse. An arbitrary number of temperature probes covering rectangular areas is also available.
