We have studied the structural and dynamical parameters of two samples of elliptical-like-objects (ELOs) formed in a set of self-consistent hydrodynamical simulations. ELO stellar masses, projected half- stellar mass radii, and stellar central l.o.s. velocity dispersions have been found to define a dynamical Fundamental Plane (FP), whose physical origin we report on.
