The Inflationary scenario was motivated to explain the large scale homogeneity of the universe. However, most of the work in this area has been carried out inhomogeneous spacetimes We present a 3D study solving Einstein's equations for inhomogeneous cosmologies to analyze the effects of matter and spacetime inhomogeneities on inflation. We use York's conformal approach to solve the initial value problem. Preliminary results of the evolution of inhomogeneous initial data are presented. 4 refs., 12 figs
