But current models can not yet model the time-dependent interplay between planetesimal collisions and dynamics. For example, they fail to accurately model patterns like the ubiquitous warps and eccentric rings, which are interactions between collisional and secular dynamical phenomena. We propose to develop a new numerical tool called "SMACK" that will model the locations of planetesimal collisions that release the dust in debris disks, the dynamical effects of these collisions, and the evolving planetesimal size-velocity distribution in 3D. We will apply this code to derive new constraints on the masses of planets orbiting Beta Pictoris and Fomalhaut, and to study the latest debris disk images from the GO 12228 STIS survey. SMACK will be made available to the community in the form of new modules for the popular, publically available REBOUND code. DEBRIS DISKS 12 Medium false false 0.0 0.0 false false true SUPPORTED
