摘要 为实现固流交互中真实感溶化现象的实时模拟,提出了基于粒子的GPU(Graphics Processing Unit)并行溶化模拟算法。利用考虑材料热传导属性的隐式热传递计算模型更新粒子温度;然后基于格子形状算法给出物体的稳定性拓扑改变方法模拟固体粒子向流体粒子的转化。为加速每个时间步内计算以达到实时性能,给出了GPU并行计算方案,并采用并行迭代填充算法来动态更新固体粒子的邻居信息。实验结果表明,所给算法在中等粒子规模下实现了真实感溶化现象的实时模拟。 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.
