Understand

We present $N$-body simulations which are fully compatible with general relativity, with dark energy consistently included at both the background and perturbation level.

We test our approach for dark energy parameterised as both a fluid, and using the parameterised post-Friedmann (PPF) formalism.
In most cases, dark energy is very smooth relative to dark matter so that its leading effect on structure formation is the change to the background expansion rate.
This can be easily incorporated into Newtonian $N$-body simulations by changing the Friedmann equation.
