Abstract
A system and method for simulating a mechanistic kinetic process, such as a chemical process including one or more chemical reactions, over a predetermined time period is provided. The simulation proceeds stochastically, by taking discrete time steps through the time period, and performing events (i.e., chemical reactions), based on the relationship between their probabilities of occurrence and the time steps taken. The system and method of the invention include means or method steps for detecting equilibrium conditions, in which a reaction moves forward and backward with a reaction probability which is high, relative to the probabilities of other reactions being simulated. When a reaction in equilibrium is detected, a probability calculation is made, based on the non-equilibrium reactions being simulated. Time steps are made, and events are simulated, based only on the non-equilibrium reactions. Thus, processing time, which would otherwise be consumed simulating back-and-forth events in the equilibrium reaction, is saved.
