Abstract

Tissue bleeding simulation is the key problem in virtual surgery, which greatly reduces the risk of real surgery. It also plays an important role in the application of fluid-solid coupling. Traditional methods of fluid-solid coupling are almost mesh-based, in this paper we proposed a tissue bleeding model as well as an improved collision detection and response algorithm based on SPH (Smoothed Particle Hydrodynamics). Our tissue bleeding model describes Navier-Stokes equations with SPH method and our tissue model is set as rigid body. Experimental results show that our coupled tissue bleeding simulation model possesses high fidelity and strong robustness.
