| Summary / Zusammenfassung | Physically based simulations are widely used in scientific visualization, virtual reality, medical applications (virtual surgery simulators) and entertainment (computer games, movie industry, etc.). In this project, we are working on the simulation and visualization of solids, fluids and gases based on a particle representation. A major challenge is the modeling of interaction processes between fluids and solids. This interaction is governed by Newtonian physics of rigid bodies as well as the Navier-Stokes equations for fluid behavior. These physical laws have to be integrated into a computational and numerical model for the computer based simulation of solid and liquid matter. In this project we analyze the physical interaction rules based on a particle system and model the interaction between particles in the system. Complex boundary conditions are also studied in the course of this project. Important aspects of computational simulation studied in this project are the numerical stability and computational efficiency of the physical simulation. With the goal of achieving plausible visual physical effects at interactive rates, fast convergence of numerical methods and optimized computations are a central topic of work. Finally, the reconstruction of fluid boundaries from particles and high-quality visualization methods are investigated to provide a convincing display mechanism of the simulated interaction processes.
