Steady-State Runge–Kutta (RK4) for Packaging

Apply the steady-state runge–kutta (rk4) to real packaging problems — in the browser, with AI assistance.

This is the steady-state variant of the Runge–Kutta (RK4). RK4 evaluates the derivative at four stages per step to achieve fourth-order accuracy, balancing accuracy and cost for non-stiff ODE systems.

In packaging, teams face challenges like drop protection, material cost, sustainability. The steady-state runge–kutta (rk4) directly supports use cases such as drop-test fea, cushioning analysis, material optimization, and PolySim's AI Copilot can recommend settings and catch common setup errors before you run.
