Optional Conditions
If the move leads to an energetic difference for example due to an electric field or an adsorbing force to the walls. In this case a Metropolis algorithm is applied: The Metroplis rate which is defined as
is compared to a random number r from the interval [0, 1). If the Metropolis rate is smaller than r the move is rejected, otherwise it is accepted.
The number of Monte Carlo steps of the total system is defined as:
