Physics-based modeling and real-time simulation

There are many simulation tools designed for specific applications. Users need to plug in application-specific parameters or models; the simulation tool will carry out simulation, graphics rendering, and animation. The article provides an extensive list of simulation tools. Simulating physics behaviors in real time presents challenging problems for scientists and graphics researchers. Such behaviors include fluids, large data materials simulations, deformable bodies, and many other complex natural phenomena. Real time simulation systems are unusual, and the best implementations are problem dependent. The article serves as an introduction to alternative modeling and simulation methods and efficiency considerations.
