Abstract

Abstract: In order to realize real-time simulation of realistic melting in fluid-solid coupling, a particle-based GPU parallel simulation method was proposed. This method employed an implicit heat diffusion model which took the heat conduction properties of materials to update the temperatures of each particle. Based on the lattice shape matching method, a stable topology change method was proposed to simulate the conversion of solid particles to the fluid particles. In order to improve the time performance of each time step, a parallel simulation method entirely implemented on GPU was put forward, and an iterative filling algorithm was designed to dynamically update each region according to the phase transition of solid particles. The results show that the method can achieve the real-time simulation of realistic melting in fluid-solid coupling for medium complex scenes.
