ABSTRACT
We present a method to efficiently simulate fluid flows through tubular structures such as pipes and blood vessels. The method relies on the structure's centerline and for that purpose we present an algorithm to generate an approximate centerline of a tubular structure defined by an ordinary polygonal mesh. As an additional benefit, this center-line provides approximations of measures about the tubular structure such as length of regions of interest and cross-section diameters. The fluid is simulated with the Smoothed Particle Hydrodynamics method and the fluid-structure interaction is simplified to provide interactive rates. The particles can be colored according to physical quantities to better visualize the evolution of the fluid's state in narrow and otherwise obstructed areas.
