It is not important to execute the simulation in real time. This technique was developed for thermal pollution forecasting. If the underlying graph is not a regular grid, the model may belong to the meshfree method class.

The remainder of the text describes

An understanding of statistical thermodynamic molecular theory is fundamental to the appreciation of molecular solutions. Equations define the relationships between elements of the modeled system and attempt to find a state in which the system is in equilibrium. Systems that accept data from external sources must be very careful in knowing what they are receiving. Simulation, therefore, is the process of running a model.

Another way of categorizing models is to look at the underlying data structures. While it is easy for computers to read in values from text or binary files, what is much harder is knowing what the accuracy compared to measurement resolution and precision of the values are. The best-known may be Simula sometimes called Simula, after the year when it was proposed. In this type of simulation, the simulator maintains a queue of events sorted by the simulated time they should occur.

Distributed models run on a network of interconnected computers, possibly through the Internet. The remainder of the text describes how to work with various protocol layers using a top-down approach. There are now many others. By contrast, computer simulation is the actual running of the program that contains these equations or algorithms. Periodically, the simulation program solves all the equations and uses the numbers to change the state and output of the simulation.

One-, two- and three-dimensional models are used. Such models are often used in simulating physical systems, as a simpler modeling case before dynamic simulation is attempted.
