Demo: Engineering Sweep, real-time polymer certification at millisecond latency

Niva’s Engineering Sweep is live on the Demos page. The demo, a web-based example of Manifold’s capabilities, runs a recycled polymer composite bearing bracket in real time, with sliders for melt temperature, recycled content blend ratio, glass fiber reinforcement, and cooling rate. Every slider movement recomputes the full physics prediction in roughly 143 milliseconds: the 3D heatmap, material properties, and FAA certification compliance all update together.

What the demo does

• Selectable visualization fields: Von Mises stress, temperature, displacement, crystallinity, and flame index.
• Material properties evaluated against aerospace certification thresholds: tensile strength, heat deflection temperature, flame rating, Izod impact, shrinkage, melt flow index, and elongation.
• Pass/fail badges against FAA FAR 25.853 thresholds. When all checks pass, the part is marked FAA Eligible.
• Three preset configurations (Baseline, High Recycled, Max Strength) plus a Find Eligible button that searches the parameter space for compliance.

Why it matters

Traditional simulation tools take hours to days per configuration. Engineers exploring a recycled polymer formulation against certification thresholds have historically faced a tradeoff: either run a small number of configurations carefully, or skip the simulation step and rely on physical prototyping. Manifold computes the same predictions in milliseconds, which changes the workflow shape entirely. Hundreds of formulations become interactively explorable. Weeks of trial-and-error compress into minutes of guided exploration.

Recycled polymer certification for aerospace is a particularly hard case: the material variability is high, the certification thresholds are strict, and the cost of a failed physical test is significant. Real-time physics prediction against certification thresholds turns a sequential, expensive process into a parallel, exploratory one.

One platform, multiple domains

Engineering Sweep is a small slice of what Manifold does. The same architecture that runs polymer certification in 143 milliseconds runs orbital state prediction at microsecond solver latency, fuses satellite Earth observation data, and handles contact-rich robotic manipulation at 60 Hz. Different domains, same platform: constitutive physics that runs continuously, deterministic solvers producing every state transition, with sensor data refining the world model.
