A simulation is the imitation of the operation of a real-world process or system over time. Simulations require the use of models; the model represents the key characteristics or behaviors of the selected system or process, whereas the simulation represents the evolution of the model over time. Often, computers are used to execute the simulation.
A train simulator is a computer based simulation of rail transport operations. They are generally large complicated software packages modeling a 3D virtual reality world implemented both as commercial trainers, and consumer computer game software with 'play modes' which lets the user interact by stepping inside the virtual world. Because of the near view modeling, often at speed, train simulator software is generally far more complicated and difficult software to write and implement than flight simulator programs.
Sim (simulated) racing or racing simulation are the collective terms for racing game software that attempts to accurately simulate auto racing, complete with real-world variables such as fuel usage, damage, tire wear and grip, and suspension settings. To be competitive in sim racing, a driver must understand all aspects of car handling that make real-world racing so difficult, such as threshold braking, how to maintain control of a car as the tires lose traction, and how properly to enter and exit a turn without sacrificing speed. It is this level of difficulty that distinguishes sim racing from "arcade" style driving games where real-world variables are taken out of the equation and the principal objective is to create a sense of speed as opposed to a sense of realism.
Ansys, Inc. is an American company based in Canonsburg, Pennsylvania. It develops and markets CAD/CAM and multiphysics engineering simulation software for product design, testing and operation and offers its products and services to customers worldwide. Ansys was founded in 1970 by John Swanson who sold his interest in the company to venture capitalists in 1993. Ansys went public on NASDAQ in 1996. In the 2000s, the company acquired numerous other engineering design companies, obtaining additional technology for fluid dynamics, electronics design, and physics analysis. Ansys became a component of the NASDAQ-100 index on December 23, 2019.
Virtutech was founded in 1998 as a spin-off from the Swedish Institute of Computer Science (SICS), in Stockholm, Sweden. In 2004, the headquarters was moved to San Jose, California, USA. The Stockholm site remains the company's R&D center. The company's main product is Simics software, used by teams of software developers to simulate computer systems. This facilitates the development, testing, and debugging of embedded software that runs devices such as high-end servers, network hardware, aerospace/military vehicles, and automobiles. Virtutech markets products that allow embedded software developers to create virtual models of hardware using an ordinary desktop computer, run specified sets of tests, and walk the programs through each step of execution, both forwards and backwards. See the Simics Wikipedia article for more on the product.
A robotics simulator is a simulator used to create application for a physical robot without depending on the actual machine, thus saving cost and time. In some case, these applications can be transferred onto the physical robot without modifications.
IMINT Image Intelligence AB, often called Imint AB, is a software company providing smartphone manufacturers with video analysis software under the trade mark Vidhance with headquarters in Uppsala, Sweden.

SimCraft, a privately held company headquartered just outside Atlanta, Georgia, is the creator of a proprietary motion simulation technology and manufactures simulation equipment integrating this technology, including professional driver in the loop racing simulators. The motion simulator technology, in development since 1998, is designed to recreate the manner in which vehicles move in earth physics. The company offers a range of simulator products in the category of motion simulation that provide a tactile true motion experience for Motorsport Simulation and flight simulation. The company's core innovation and technology is the simulation of vehicle movement through proprietary physics based software interfaces and a patent pending hardware architecture based on Center of Mass principles of motion. The company's product applications range principally by variation in chassis design and material and are found in usage from military training/research, professional training, to individual simulation and gaming enthusiast entertainment.
Amateur flight simulation refers to the simulation of various aspects of flight or the flight environment for purposes other than flight training or aircraft development. A significant community of simulation enthusiasts is supported by several commercial software packages, as well as commercial and homebuilt hardware. Open-source software that is used by the Aerospace industry like FlightGear, whose flight dynamics engine (JSBSim) is used in a 2015 NASA benchmark to judge new simulation code to space industry standards, is also available for amateur use. A popular type of amateur flight simulators are combat flight simulators, which simulate combat air operations from the pilot and crew's point of view. Combat flight simulation titles are more numerous than civilian flight simulators due to variety of subject matter available and market demand.
rFactor 2 is a computer racing simulator developed by the American independent software firm Image Space Incorporated and released for Windows in 2012. Like its predecessor, rFactor, it is designed to be modified and is used by professional racing teams for driver training and race car development. Much of its source code is derived from rFactor Pro which is also used by professional racers and most of the Formula One teams and NASCAR manufacturers.
