direct simulation Monte Carlo[də¦rekt ‚sim·yə¦lā·shən ¦män·tə kär·lō]
An iterated two-step procedure for simulation of fluid flow, in which the calculation of the outcomes of collisions of paired particles based on intermolecular potentials alternates with the partitioning of the phase space into cells and the random selection of 10-100 particle pairs as candidates for collision, consistent with collision frequency predictions based on kinetic theory.
