Summary:In this work we study the cosmological simulations as a tool to understand the formation of large-scale structure of the universe, for this, we show the equivalence of Newtonian cosmology with Poisson gauge and we study the solution of the Einstein's field equations for this gauge. The simulations are essential for taking account the results of the cosmological model, allowing to compare the results with observational data. The N-bodies simulations have been used from systems of few bodies to the evolution and formation of nonlinear large scale structure as filaments and galactic halos.
