Abstract: We present results from extensive numerical simulations of phase ordering dynamics in a mean-field dynamical model of weakly disordered random magnets. We apply a stringent test of dynamical scaling to confirm that the domain growth is superuniversal, i.e., the scaling function for the disordered case is the same as for the pure case, at least for the disorder amplitudes we consider. However, we are not able to ascertain a universal functional form for the domain growth law.
