Visual simulation of underwater explosion considering water surface change

Abstract

In this paper, we propose a visual simulation method for underwater explosions considering water surface changes based on Shallow Water Simulation using the particle method. The shock wave is simulated by solving the shock wave equation using a combination of the Adomian decomposition method (an analytical method) and the semi-Lagrangian method (a numerical method), and the method adds the representation of splashes by 3D particles to Shallow Water Simulation, which can simulate fluids at high speed. We propose a method to reproduce changes in the water surface caused by explosions. The effectiveness of the proposed method was verified by implementing it and reproducing an underwater explosion scene in CG as an experiment.
