KIC 9406652, one of the recently identified IW And-type dwarf novae, is thebest target for studying the tilted disk in cataclysmic variable stars. In aprevious paper by Kimura, Osaki, and Kato (2020), we analyzed its Kepler lightcurves and found that its orbital light curves during the brightening stagewere dominated by the reflection effect of the secondary star and varied withthe orientation of the tilted disk; the amplitude was maximized at the minimumof the super-orbital signal and the phase of the light maximum shifted to anearlier one with the advance of the super-orbital phase. We argued there thatthis was the direct evidence of the retrogradely precessing tilted disk as thesecondary star acts like a reflecting object. In order to confirm thisinterpretation, we have performed numerical modeling of orbital light curves inthis paper. We have succeeded in reproducing the main characteristics of theobserved orbital light curves by a simple model in which the secondary star isirradiated by the tilted disk. We have also constrained the inclination angle,$i$, of the binary system and the tilt angle, $\theta$, of the disk purely fromphotometric considerations. The best-fitting parameter set is found to be $i\sim$45~deg and $\theta \sim$2.0~deg, respectively. The orbital inclinationthus estimated is consistent with that obtained from the spectroscopicconsiderations within the uncertainty limit. On the other hand, the tilt angleof the disk could be underestimated by using only the semi-amplitude ofsuper-orbital signals.
