Blood Flow SPH Simulation with Elastic Deformation of Blood Vessels

Blood vessels are responsible for the distribution of nutrients and oxygen to all cells in the human body. Due to advances in technological research, many medical applications that use 3d objects are being developed to assist specialists. With the aim of increasing the physical realism of 3D simulations in this scenario, our approach combines Smooth Particle hydrodynamics methods and mass-spring to simulate elastic deformations in the blood vessels during the circulation of the blood. The results, although partial, indicate that the deformation visualization is compatible with the expected physical behavior in a real situation. Additionally, we also observed that the behavior of the flow is different when considering a vessel with rigid walls, which is the case most of the related work.
