中文导读
SpaceX 工程师在 NVIDIA GTC 大会上公开用于模拟 Raptor 猛禽全流量分级燃烧甲烷发动机的多物理场自研仿真系统，展示了基于 GPU 的自适应网格细化与小波压缩湍流燃烧模拟技术。
为什么 HN 推它
展现 SpaceX 顶尖自研工业仿真能力的代表作，也是 GPU 高性能计算在计算流体力学（CFD）领域落地的典范案例。
「这是 2015 年 NVIDIA GTC 上的演讲，正是它启发了我后来投身先进制造领域。」HN 网友原话：This talk was given at NVIDIA GTC 2015 and inspired me to go into manufacturing
英文原摘要（HackerTube / Claude 整理）
SpaceX engineers present at NVIDIA's GPU Technology Conference on a multi-physics code that simulates the full-scale Raptor methane engine. It covers GPU-based turbulent combustion modeling with adaptive grids and wavelet compression.
HN points to it as evidence of SpaceX's serious simulation capability and as a showcase of GPU compute for CFD.
