I will first give an introduction to the field of Nbody numerical simulations presenting results for a standard cosmological constant scenario. I will then show at which extent the process of structure formation is affected by the nature of Dark Energy (DE). I will present results for several possible parametrization of DE, from simple time-varying dark energy to more complex models where DE varies both in space and time and its coupled to Dark Matter. Finally some possible observational tests will be discussed.
