Simulation of Fluid-Solid Interaction
نویسنده
چکیده
This thesis proposes a way to simulate the interaction of fluids and solids based on the Smoothed Particle Hydrodynamics method. The interaction is facilitated by not only representing fluids with particles, but solid objects as well. Linear elastic forces are computed between neighbouring particles to create deformable objects. The animation of fully rigid objects is made possible by introducing rigid body dynamics into the simulation, which restricts rigid particles to translations and rotations about the centre of mass of their object. With the objects consisting of particles, solids can melt by removing hot particles, and fluids can freeze by forming new objects from cold particles.
