D Electromagnetic Simulation Software Open Source' title='3D Electromagnetic Simulation Software Open Source' />Simulation Wikipedia. D simulation of a Grain Terminal Model. Simulation is the imitation of the operation of a real world process or system over time. 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. Simulation is used in many contexts, such as simulation of technology for performance optimization, safety engineering, testing, training, education, and video games. Often, computer experiments are used to study simulation models. Simulation is also used with scientific modelling of natural systems or human systems to gain insight into their functioning,2 as in economics. Simulation can be used to show the eventual real effects of alternative conditions and courses of action. This list of 3D graphics software contains software packages related to the development and exploitation of 3D computer graphics. For a comparison see Comparison of. Simulation is also used when the real system cannot be engaged, because it may not be accessible, or it may be dangerous or unacceptable to engage, or it is being designed but not yet built, or it may simply not exist. Key issues in simulation include acquisition of valid source information about the relevant selection of key characteristics and behaviours, the use of simplifying approximations and assumptions within the simulation, and fidelity and validity of the simulation outcomes. Procedures and protocols for model verification and validation are an ongoing field of academic study, refinement, research and development in simulations technology or practice, particularly in the field of computer simulation. Classification and terminologyeditHistorically, simulations used in different fields developed largely independently, but 2. Physical simulation refers to simulation in which physical objects are substituted for the real thing some circles4 use the term for computer simulations modelling selected laws of physics, but 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. Simulation Fidelity is used to describe the accuracy of a simulation and how closely it imitates the real life counterpart.

Fidelity is broadly classified as 1 of 3 categories low, medium, and high. 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. Simulation in failure analysis refers to simulation in which we create environmentconditions to identify the cause of equipment failure. This was the best and fastest method to identify the failure cause. Computer simulationeditA 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. D Electromagnetic Simulation Software Open Source' title='3D Electromagnetic Simulation Software Open Source' />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. Computer simulation has become a useful part of modeling many natural systems in physics, chemistry and biology,6 and human systems in economics and social science e. 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 model, which 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 modeling, multimethod modeling that makes all the modeling almost effortless. Modern usage of the term computer simulation may encompass virtually any computer based representation. Computer scienceeditIn computer science, simulation 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 machinecitation needed. The computer simulates the subject machine. Accordingly, in theoretical computer science the term simulation is a relation between state transition systems, useful in the study of operational semantics. Less theoretically, an interesting application of computer simulation is to simulate computers using computers. In computer architecture, a type of simulator, typically called an emulator, is 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 available, or 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.

Since the operation of the computer is simulated, all of the information about the computers operation is directly available to the programmer, and the speed and execution of the simulation can be varied at will. Simulators may also be used to interpret fault trees, or test VLSI logic designs before they are constructed. Symbolic simulation uses variables to stand for unknown values. In the field of optimization, simulations of physical processes are often used in conjunction with evolutionary computation to optimize control strategies. Simulation in education and trainingeditSimulation is extensively used for educational purposes. It is frequently used by way of adaptive hypermedia. Simulation is often used in the training of civilian and military personnel. This usually occurs when it is prohibitively expensive or simply too dangerous to allow trainees to use the real equipment in the real world. In such situations they will spend time learning valuable lessons in a safe virtual environment yet living a lifelike experience or at least it is the goal. Often the convenience is to permit mistakes during training for a safety critical system. There is a distinction, though, between simulations used for training and Instructional simulation.
