Real-time fluid simulation with complex boundary based on slice voxelization method

Abstract

In view of the present restriction in complex boundary interaction in real time fluid simulation. A physically based real-time fluid simulation method with complex boundary is proposed and implemented. The pressure projection algorithm is used to solve the N-S equation. The implicit scheme is employed to guarantee the stability of the nonlinear advection term. This paper presents and implements the idea of slicing and voxelization of the solid boundary in a unified way. The algorithm is independent of the specific model, which can simulate the fluid interaction with complex boundary flow field of different 3D models efficiently.
