摘要：
We present cosmological-scale numerical simulations of an evolving universe in full general relativity and introduce a new numerical tool, COSMOGRAPH, which employs the Baumgarte-Shapiro-Shibata-Nakamura formalism on a three-dimensional grid. Using COSMOGRAPH, we calculate the effect of an inhomogeneous matter distribution on the evolution of a spacetime. We also present the results of a set of standard stability tests to demonstrate the robustness of our simulations.
