Visualization of a direct numerical simulation model. Historically, simulations used in different fields developed largely independently, but 20th century studies of systems theory and cybernetics combined with spreading use of computers across all those fields have led to some unification and a more systematic view of the concept.

Physical simulation refers to simulation in which physical objects are substituted for the real thing some circles [4] use the term for computer simulations modelling selected laws of physicsbut this article does not.

These physical objects are often chosen because they are smaller or cheaper than the actual object or system.

Interactive simulation is a special kind of physical simulation, often referred to as a human in the loop simulation, in which physical simulations include human operators, such as in a flight simulator or a driving simulator. Continuous simulation is a simulation where time evolves continuously based on numerical integration of Differential Equations.

Hybrid Simulation sometime Combined Simulation corresponds to a mix between Continuous and Discrete Event Simulation and results in integrating numerically the differential equations between two sequential events to reduce number of discontinuities [7] Stand Alone Simulation is a Simulation running on a single workstation by itself.

Fidelity is broadly classified as 1 of 3 categories: Specific descriptions of fidelity levels are subject to interpretation but the following generalization can be made: Low — the minimum simulation required for a system to respond to accept inputs and provide outputs Medium — responds automatically to stimuli, with limited accuracy High — nearly indistinguishable or as close as possible to the real system Human in the loop simulations can include a computer simulation as a so-called synthetic environment.

This was the best and fastest method to identify the failure cause. Computer simulation A computer simulation or "sim" is an attempt to model a real-life or hypothetical situation on a computer so that it can be studied to see how the system works.

By changing variables in the simulation, predictions may be made about the behaviour of the system.

It is a tool to virtually investigate the behaviour of the system under study. A good example of the usefulness of using computers to simulate can be found in the field of network traffic simulation.

In such simulations, the model behaviour will change each simulation according to the set of initial parameters assumed for the environment.

Traditionally, the formal modeling of systems has been via a mathematical modelwhich attempts to find analytical solutions enabling the prediction of the behaviour of the system from a set of parameters and initial conditions. Computer simulation is often used as an adjunct to, or substitution for, modeling systems for which simple closed form analytic solutions are not possible.

There are many different types of computer simulation, the common feature they all share is the attempt to generate a sample of representative scenarios for a model in which a complete enumeration of all possible states would be prohibitive or impossible.

Several software packages exist for running computer-based simulation modeling e. Monte Carlo simulation, stochastic modelingmultimethod modeling that makes all the modeling almost effortless.

Modern usage of the term "computer simulation" may encompass virtually any computer-based representation. Computer science[ edit ] In computer sciencesimulation has some specialized meanings: Alan Turing used the term "simulation" to refer to what happens when a universal machine executes a state transition table in modern terminology, a computer runs a program that describes the state transitions, inputs and outputs of a subject discrete-state machine.

Accordingly, in theoretical computer science the term simulation is a relation between state transition systemsuseful in the study of operational semantics.

Simulation - Wikipedia

Less theoretically, an interesting application of computer simulation is to simulate computers using computers. In computer architecturea type of simulator, typically called an emulatoris often used to execute a program that has to run on some inconvenient type of computer for example, a newly designed computer that has not yet been built or an obsolete computer that is no longer availableor in a tightly controlled testing environment see Computer architecture simulator and Platform virtualization.

For example, simulators have been used to debug a microprogram or sometimes commercial application programs, before the program is downloaded to the target machine. Simulators may also be used to interpret fault treesor test VLSI logic designs before they are constructed.The RNA-Binding Protein of a Double-Stranded RNA Virus Acts Like a Scaffold Protein.

A simulation is an imitation of the operation of a real-world process or system. The act of simulating something first requires that a model be developed; this model represents the key characteristics, behaviors and functions of the selected physical or abstract system or process.

The model represents the system itself, whereas the simulation represents the operation of the system over time.
