Explicit Semi-Lagrangian Advection for Defense
Apply the explicit semi-lagrangian advection to real defense problems — in the browser, with AI assistance.
This is the explicit variant of the Semi-Lagrangian Advection. Semi-Lagrangian schemes trace characteristics backward in time and interpolate, giving stability at large timesteps — the basis of Stam's Stable Fluids.
In defense, teams face challenges like blast and impact, signature management, reliability. The explicit semi-lagrangian advection directly supports use cases such as ballistic fea, aerodynamics, electromagnetic modeling, and PolySim's AI Copilot can recommend settings and catch common setup errors before you run.
Typical Defense use cases
- Ballistic FEA
- Aerodynamics
- Electromagnetic modeling
