    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.

    1. @paulsutterOct 2024· in “Can SpaceX land a rocket with 1/2 cm accuracy?”

      The key was the full scale combustion simulator software that SpaceX developed to design the Raptor. This talk was given at NVIDIA GTC 2015 and inspired me to go into manufacturing this video title: "GPUs To Mars: Full Scale Simulation of SpaceX's Mars Rocket Engine"

    2. @danielvfSep 2022· in “Some things I realized about AI while contemplating slide rule prices on eBay”

      Or maybe it is that SpaceX is doing simulations on a level ahead of what everyone else does. Here's one of several amazing videos from SpaceX simulations. (There are more, but I don't have the link to the others) this video

    3. @T-AJul 2015· in “Ask HN: What companies are doing work related to scientific computing?”

      Here's a fun recent link: this video Plenty more options to explore in the links under the video, starting from [LINK] Then there is NVIDIA's CUDA Zone with lists like [LINK]

    4. @swimfarMay 2019· in “Trump Administration Might “Re-Examine” Climate Modeling”

      I remember that. Fluid dynamics is a very tricky thing to model and the work they did was really cool. There's a good video presentation on it here: this video

    5. @cmaDec 2015· in “The first plasma: the Wendelstein 7-X fusion device is now in operation”

      There are bigger optimizations than 10X with some of the adaptive grid / wavelet compression stuff. I think these are still 2D, but pretty amazing: this video
