Using smoothed particle hydrodynamics, we numerically simulate steady state accretion disks for Cataclysmic Variable Dwarf Novae systems that have mass ratios between 0.35 < q < 0.55. We simulate negative superhumps and retrograde precession by tilting quasi-steady state accretion disks various degrees out of the orbital plane. We study these tilted disks to find effects of disk tilt and mass ratio on the amplitudes of modulated light in light curves known as negative superhumps and to find that portion of the accretion disk that powers the negative superhumps. In this talk, we compare our numerical simulation results with observational data and we discuss some of our findings. We acknowledge the UCF/UF Space Research Initiative and the AAS Small Research Grants.
