Description
We present the preliminary results of cosmological simulation focused on the study of the size and velocity dispersion time evolution. We have study the main morphological features of a sample of more that 200 galaxies having masses between 5 x 10^{10} M_&sun; and 5 x 10^{11} M_&sun;. We compared the results obtained from the analysis of the simulated sample with the observational data. The time evolution of size and velocity dispersion of simulated galaxies seems to go in the right direction, pointing observational results, leading to the conclusion that the cause of such morphological evolution could be due to the minor merger events and the
