nTop | Computational Design Software

Accelerate how fast you move from requirements to design.

nTop eliminates traditional design bottlenecks—capture engineering logic, iterate instantly, simulate as you design, and explore 10x faster with parametric models that never break.

Engineering is being outpaced by its own ambition.

Product development timelines are shrinking. Performance demands are rising. Yet most teams still rely on brittle tools that force early design lock-in before tradeoffs are explored or risks understood. With nTop, you can generate, explore, and validate geometry automatically, insightfully, and without fragility to meet mission requirements.

Traditional CAD Process

model → test → rework

CAD models that can’t adapt as requirements shift
Simulation as a bottleneck, not a guide
Architecture decisions made on assumptions

nTop Process

define → explore → validate

Geometry that adapts as constraints evolve.
Simulation in the loop, not as an afterthought.
Logic you can trace, audit, and adapt.

Design faster. Decide smarter. Deliver with confidence.

Whether in early research, iterative development, or production optimization, nTop accelerates engineering workflows at every stage

Why nTop works where other tools break

nTop accelerates iteration and empowers high-confidence decisions across every design phase. Here’s how leading teams apply it:

Iterate without fragile geometry

Logic-driven modeling means no crashes, rebuilds, or rework. Make changes instantly, even to complex models, and explore 10x more options without debugging.

Simulate while you design

With embedded FEA and CFD in the loop, you get physics insight as you build, reducing trial and error and surfacing risks before they cost you.

Scale your design logic

Capture engineering intent once and reuse it across variants, missions, and programs. What used to be tribal knowledge becomes shareable, adaptable design code.
