A numerical study of a quenched complex field vvith a rotationally symmetric (<)'-type) local free energy is performed by use of a coupled map lattice model. Wevisualize the time evolution of a quenched systena especially the dynamics of linedefects, i.e. vortex lines. A power law about the evolution of the defect density is con-firmed to hold. In the case of deep quench, it is found that at the late stage of theevolution process, many defect lines are formed and their total length N decreases-0.75fO.05with time as ,/Vll)C t 111 a wide range of time. On the contrary, in the case ofshallow quench, the evolution process is quite different from that of the former case,namely only few topological defects are formed and the system approaches to thefinal state much faster than it does in the former case.
