3D Semi-Lagrangian Advection for Nuclear
Apply the 3d semi-lagrangian advection to real nuclear problems — in the browser, with AI assistance.
This is the 3d 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 nuclear, teams face challenges like neutron transport, thermal-hydraulics, safety margins. The 3d semi-lagrangian advection directly supports use cases such as reactor kinetics, shielding attenuation, decay-heat modeling, and PolySim's AI Copilot can recommend settings and catch common setup errors before you run.
Typical Nuclear use cases
- Reactor kinetics
- Shielding attenuation
- Decay-heat modeling
