A numerical simulation is a calculation that is run on a computer following a program that implements a mathematical model for a physical system. Numerical simulations are required to study the behaviour of systems whose mathematical models are too complex to provide analytical solutions, as in most nonlinear systems.
Studies of vocal production in baleen whales show that their larynx has evolved unique structures that enable their low-frequency vocalizations but limit their active communication range.
The means by which supermassive black holes form and grow have remained largely unclear. Numerical simulations show that the collision of massive galaxies can naturally lead to the creation of these objects.
The sequence of events during the collision between India and Eurasia has long been contested. Numerical simulations imply that the key to the puzzle could lie in the subduction of continental lithosphere.
