Abstract
Numerical simulation of the evolution of two or more interacting galaxies requires a fine spatial resolution to resolve detail in individual systems. The much larger regions separating the galaxies must be treated in the same detail with current fast Fourier transform based potential solvers. This paper describes a mesh segmentation technique which permits us to solve very large potential problems and to concentrate our effort on the regions where detailed potential maps are required. We discuss the need for this method in simulating single disc galaxies, and in the study of galactic collisions.
