Explicit Semi-Lagrangian Advection for Manufacturing

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 manufacturing, teams face challenges like process defects, thermal warping, throughput. The explicit semi-lagrangian advection directly supports use cases such as injection-molding flow, additive thermal history, machining stress, and PolySim's AI Copilot can recommend settings and catch common setup errors before you run.
