Rigid Body Sampling and Individual Time Stepping for Rigid-Fluid Coupling of Fluid Simulation

الملخص EN

In this paper, we propose an efficient and simple rigid-fluid coupling scheme with scientific programming algorithms for particle-based fluid simulation and three-dimensional visualization.

Our approach samples the surface of rigid bodies with boundary particles that interact with fluids.

It contains two procedures, that is, surface sampling and sampling relaxation, which insures uniform distribution of particles with less iterations.

Furthermore, we present a rigid-fluid coupling scheme integrating individual time stepping to rigid-fluid coupling, which gains an obvious speedup compared to previous method.

The experimental results demonstrate the effectiveness of our approach.
