Cosmological Nbody simulations.
Abstract
The authors discuss cosmological Nbody codes with a special emphasis on particle mesh codes. They present the mathematical model for each component of Nbody codes. They compare alternative methods for computing each quantity by calculating errors for each of the components. The authors suggest an optimum set of components that can be combined to reduce the overall errors in Nbody codes.
