Physics-Informed Neural Surrogates for Mesh-Invariant Modeling of High-Speed Flows at #AIAA #SciTech!

High-speed flight simulation is computationally brutal. A single CFD run can take hours on a cluster. That's fine for final validation, but not for early design exploration or real-time decision-making.

Neural surrogate that predicts aerodynamic behavior 595x faster than CFD while maintaining ~1% relative error.

One thing I’ve noticed at #aiaaSciTech is an increasing role of #Python in modeling and analysis toolchains. I used to think matlab/simulink had a stranglehold on engineering as a discipline, but that’s really not true anymore

Both Parrish and Michael Meyer, Mars Exploration Program lead scientist, say they expect future robotic Mars spacecraft (beyond sample return) to trend towards smaller, more focused (and cheaper) missions. #AIAASciTech

We were warned to attempt no landings there. (Seen at #AIAASciTech)
