With increasing accuracy of CMB data, a thorough, quantitative understanding of the post-inflationary reheating era becomes more and more important for constraining different models of inflation. In particular, a precise computation of the non-homogeneous field evolution during preheating is desirable.In this talk I will present results of such computation for single field inflation model based on alpha-attractors models of inflation. I will show the Floquet analysis of field perturbations evolution, as well as results of full non-linear simulations of the field evolution. I will discuss the importance of studying the dynamics of both scalar fields present in the model.
