Monte Carlo method


In modeling and simulation, any method that employs Monte Carlo simulation in which random statistical sampling techniques are employed such that the result determines estimates for unknown values´╝Ä

Monte Calro method is used, for example, for simulation of collision of gas molecules onto solid surface. In this method, molecules are sampled randomly from the huge number of gas molecules existing in the objective region of computation, and their motion is analyzed according to the law of probabilities to determine the flow field. Recently, the technique has advanced and is called the direct simulation Monte Carlo method, which can treat collisions of gas molecules not only against solid surface but also with each other.
