Two large sets of ray-tracing simulations are carried out for 10 massive clusters at two redshifts, i.e. $z_{\\rm l} \\sim 0.2$ and 0.3. The virial mass ($M_{\\rm vir}$) of the simulated lens clusters at $z\\sim0.2$ ranges from $6.8\\times10^{14} h^{-1} {M_{\\odot}}$ to $1.1\\times 10^{15} h^{-1} M_{\\odot}$.
