Accelerate design space exploration and program delivery

From DARPA SPRINT X-plane development to MV-75 production acceleration—compress design cycles from months to minutes while maintaining technical confidence.

Trusted by 450+ leading engineering teams


Three Critical Challenges.
One Proven Approach.

MV-75

Accelerate Delivery of Performance-Critical Components

Performance-critical components require rapid design space exploration under compressed schedules. Traditional tools bottleneck: 4-8 hours manual prep per iteration, CAD failures during parametric changes, days per design cycle.

Explore hundreds of component variants with integrated multi-physics analysis. Compress design cycles from weeks to days with unbreakable parametric modeling.

DARPA SPRINT X-PLANE

Deliver On Schedule With Technical Confidence

Transitioning from preliminary to detailed design demands robust parametric modeling that survives continuous refinement, requiring iterative optimization cycles that traditional CAD cannot support without constant manual intervention.

Generate analysis-ready geometry across design iterations. Run overnight MDO studies with zero geometry failures. Validate design decisions with integrated physics before hardware commitments.

NATO NGRC

Win Through Comprehensive Concept Exploration

Winning competitive concept studies demands demonstrating systematic exploration across the design space—not 3-5 hand-picked configurations.

Explore hundreds of configuration variants with integrated multi-disciplinary analysis. Generate Pareto frontiers showing optimal trade-offs across speed, range, payload, and cost. Prove methodology rigor that builds program office confidence.

How nTop Accelerates Bell's Critical Programs

Unbreakable Parametric Modeling

model → test → rework

Traditional B-rep CAD fails during large parametric changes in tiltrotor design. Modify parameters and feature trees break, requiring hours to days of manual repair. nTop uses implicit modeling instead of fragile boundary representations. Parametric changes propagate instantly with zero topology failures.

Integrates with Your Existing Toolchain

define → explore → validate

  • FEA/CFD: ANSYS, Star-CCM+, Nastran—export analysis-ready geometry with zero manual cleanup
  • MDO: ModelCenter, HEEDS, OpenMDAO—parametric models integrate directly into optimization loops

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 while you design

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.


Broader exploration. Better Designs.

nTop lets you explore more design variants, faster, and pick the top performer with confidence.
