Field-Driven Design

Take your engineering product development to the next level.

Convert Physics to Geometry

Every physical quantity can be described as a field; from simulation results and experimental data, to the geometry of a solid body. nTop Field-Driven Design platform gives engineers the unique ability to convert the basic, underlying physics that guide a process into accurate part geometry with Field-Driven Design.


Take Absolute Control

By combining fields with a groundbreaking approach to modeling, nTop Platform enables engineers to design transformative products that were previously impossible. Our design software gives you the tools you need to create any geometry imaginable without any technical boundaries.

Generative Product Design

Let data and simulations drive your design process. Our Field-Driven Design platform can lead your engineering product development team to directions that you could have not even thought of on day one.


Case Study

Re-Imagining the Engine Cylinder with Field-Driven Design

The engineers of Cobra Aero used multiphysics simulation to account for factors like temperature, air-flow, mechanical stresses, and pressure to design an optimal air-cooled cylinder for the thermal-combustion engine of their military-grade UAV.

FAQ on Field-Driven Design


What are fields?

To put it simply, fields are data. Any quantity that can be mapped in space to a binary or scalar value is a field. Examples of fields include CAD geometry, simulation results, experimental data, and manufacturing process knowledge.

How do I create a field?

All part, mesh, surface, and curve geometry becomes a field based on the signed distance to the part, leading to error free modeling operations. Fields important to mechanical design, such as stress and pressure, can be created by exporting the results of a simulation or tabulated data, or analytical formula, either created in nTop Platform or imported from external software and mapping appropriately the units.

Can I combine fields from different physics?

The ability to easily couple diverse simulation results with empirical data and analytical formulas is uniquely facilitated by Field-Driven Design. The results of different simulations can be easily imported in nTop Platform and appropriately mapped and weighted to create a single field that drives the geometry.

What happens if my field has noise or singularities?

Noisy data can be smoothed easily in nTop Platform using pre-configured blocks. Singularities are common when defining fields in fluid mechanics. When used to drive geometry, they can be capped to a user-defined maximum value.

How is our Field-Driven Design platform better than features, parameters, and other relationships expressed in “traditional” CAD?

Mates and relations are great for simple parts with geometries that do not change often but fall short when things get more complex. Fields in nTop Platform directly drive the mathematical representation of a part based on physics, manufacturing conditions, and surrounding geometry, and never fail to compute no matter how complex the geometry is or how radically the design changes.
