Project Overview
This project is a C++ dark-matter-only cosmological N-body implementation. Its objective is to implement standard ΛCDM structure formation reproducibly and to test initial conditions, periodic gravity, time integration, restart continuation, and derived analysis products under controlled numerical changes.
