By saying uniformly distributed, I mean the temperature in the middle area (free to MD run) is supposed to distributed uniformly. If u think it has to be guass type,why do u think so?
In molecular simulation, the two sides (X direction) of the simulating system has fixed temperature 300 k. The middle area is free to any constraint. Then we add a electrical field to the system along X direction. After some time steps,the temperature distribution along X direction looks like...
