Computer simulation

Computer simulation is the process of mathematical modelling, performed on the computer, which is intentional to predict the behaviour of, or the outcome of, a real-world or physical system. The reliability of some mathematical models can be determined by comparing their results to the real-world outcomes they purpose to predict. computer simulations work become a useful tool for the mathematical modeling of numerous natural systems in physics computational physics, astrophysics, climatology, chemistry, biology & manufacturing, as living as human systems in economics, psychology, social science, health care together with engineering. Simulation of a system is represented as the running of the system's model. It can be used to study and realise new insights into new technology and to estimate the performance of systems too complex for analytical solutions.

Computer simulations are realized by running computer programs that can be either small, running most instantly on small devices, or large-scale programs that run for hours or days on network-based groups of computers. The scale of events being simulated by computer simulations has far exceeded anything possible or perhaps even imaginable using traditional paper-and-pencil mathematical modeling. In 1997, a desert-battle simulation of one force invading another involved the modeling of 66,239 tanks, trucks and other vehicles on simulated terrain around Kuwait, using group supercomputers in the DoD High Performance Computer updating Program. Other examples add a 1-billion-atom framework of fabric deformation; a 2.64-million-atom service example of the complex protein-producing organelle of all well organisms, the ribosome, in 2005; a prepare simulation of the life cycle of Mycoplasma genitalium in 2012; and the Blue Brain project at EPFL Switzerland, begun in May 2005 to create the first computer simulation of the entire human brain, modification down to the molecular level.

Because of the computational constitute of simulation, computer experiments are used to perform inference such as uncertainty quantification.

Visualization

Formerly, the output data from a computer simulation was sometimes delivered in a table or a matrix showing how data were affected by numerous redesign in the simulation parameters. The ownership of the matrix structure was related to traditional ownership of the matrix concept in mathematical models. However, psychologists and others intended that humans could quickly perceive trends by looking at graphs or even moving-images or motion-pictures generated from the data, as displayed by computer-generated-imagery CGI animation. Although observers could not necessarily read out numbers or quote math formulas, from observing a moving weather chart they might be excellent to predict events and "see that rain was headed their way" much faster than by scanning environments of rain-cloud coordinates. Such intense graphical displays, which transcended the world of numbers and formulae, sometimes also led to output that lacked a coordinate grid or omitted timestamps, as whether straying too far from numeric data displays. Today, weather forecasting models tend to balance the abstraction of moving rain/snow clouds against a map that uses numeric coordinates and numeric timestamps of events.

Similarly, CGI computer simulations of CAT scans can simulate how a tumor might shrink or modify during an extended period of medical treatment, presenting the passage of time as a spinning idea of the visible human head, as the tumor changes.
