Abstract

Previous contact handling methods for Smoothed Particle Hydrodynamics (SPH) cannot guarantee the absence of penetrations when fluid interacts with cloth at high velocity. Thus we propose a novel fluid/cloth coupling method that treats the coupled system robustly, accurately and efficiently. We designed a dilated continuous collision detection algorithm which is capable of detecting collisions between fluid and cloth accurately, and a penalty-based contact force algorithm to untangle the collision pair. Compared with previous fluid/cloth coupling methods, our method has solved the problems that penetrations occur when fluid interacts at cloth with high velocity, and the force field in the computational domain becomes discontinuous at the connections of cloth elements. Experiments proved that the simulation result is reasonable, and our method is light-weighted, efficient, and general. It can be used as a complementary tool for fluid/cloth simulation and applicable to other particle-based simulations.
