In the earliest stages of relativistic heavy-ion collisions, nuclei can be described as color glass condensates (CGCs). The CGC is an effective description of high energy nuclear matter in terms of classical color fields and sources. The collision of two such CGCs produces a quasi-classical field known as the Glasma, which is a precursor to the quark gluon plasma. Simulations of such collisions are usually performed in the ultrarelativistic limit, where the system exhibits boost invariance and can be considered to be effectively 2+1 dimensional. In this poster we present our approach to go beyond the boost invariant approximation and simulate the creation and the evolution of the Glasma in 3+1 dimensions. In particular, we present improvements to the numerical method used to solve the classical Yang-Mills equations. Using a semi-implicit scheme, we are able to eliminate unphysical wave dispersion along the beam axis thus enabling more stable and accurate simulations.
