Gadget Description
Monday, February 4, 2008 | | |Gadget is a code freely available for N-body/SPH cosmological simulations on massively parallel computers memory distributed. HO explicit uses a model of communication which is implemented with the standard MPI communication interface. The code can be run on almost all the super-systems currently in use, including groups of individual workstations or PCs.
HO calculates gravitational forces with a hierarchical tree algorithm (possibly in combination with a mesh-particle system for long-range gravitational forces) and represents fluids through smoothed particle hydrodynamics (SPH). The code can be used for studies of isolated systems, or simulations that include the cosmic expansion of space, whether with or without periodic boundary conditions. In all these types of simulations, gadget follows the evolution of a self-revolving collisionless N-body, and allows the dynamics of gas may be included. Both the strength of calculation and strengthen time gadget are fully coping with a dynamic range that is, in principle, unlimited.
Gadget can be used to treat a wide range of astrophysically interesting problems, ranging from collision and merging galaxies, the formation of large-scale structure in the universe. With the inclusion of other physical processes such as radiation cooling and heating, gadget can also be used to study the dynamics of gas intergalactic medium to address star formation and its regulation by feedback process .
