Simulation

Simulation that keeps pace with iteration

Embed simulation directly into design exploration workflows—run structural, thermal, and CFD analysis on parametric implicit geometry without meshing delays. Scale fidelity from GPU-accelerated LBM CFD to traditional high-fidelity solvers—all using the same parametric foundation.

Explore more than a handful of variants


Design space exploration requires evaluating configurations across your design space, but any manual step creates a bottleneck that collapses exploration from thousands of possibilities to just a few.

nTop eliminates delays by embedding simulation into reusable workflows that require minimal hands-on preparation—validate hundreds of configurations and catch problems when changes cost hours instead of months.

Fluid flow at the speed of exploration

GPU-accelerated CFD to evaluate hundreds of configurations

nTop Fluids uses GPU-accelerated LBM CFD for internal flow and external aerodynamics (up to Mach 0.7) with simple setup that doesn’t require a conformal mesh, enabling rapid design space exploration.

Structural FEA that follows every change

Catch issues early, when changes are easy

nTop's integrated FEA includes stress, displacement, modal, thermal, and topology optimization. Parametric changes automatically update the mesh and boundary conditions, enabling a closed loop process for design optimization.

Feed trusted solvers without intervention

Connect high-fidelity CAE to parametric exploration

Export analysis-ready geometry to traditional CFD, FEA, and MDO tools. Automated, high-quality export reduces the need for manual repair and enables parametric studies where traditional workflows break down.

Run physics directly on implicit geometry

Eliminate translation overhead entirely

Partner integrations with Intact.Simulation, SimScale, and Voxshell operate natively on nTop implicit geometry—no conversion or surface meshing required, so model integrity is maintained throughout the analysis chain.


Explore broader. Decide with confidence.

nTop simulation eliminates the sequential bottlenecks that force early lock-in decisions based on incomplete understanding.

Lower analysis failure rates

Reduce rates that limit analysis throughput with reliable geometry and model prep.

Evaluate your entire design space

Fast setup and GPU acceleration enable evaluating hundreds or thousands of configurations.

Minimize manual effort

Parametric changes refresh calculations and results without model rebuilds or cleanup.

Identify potential risks early

Catch design issues when changes cost hours instead of months.


Scale fidelity across the design process

nTop simulation can provide more granular insights using the same parametric foundation to compress iteration cycles at every stage.

Low-fidelity

Embed equations directly so changes update calculations instantly.

Medium-fidelity

Run embedded CFD and FEA directly on implicit geometry.

High-fidelity

Automate the export of analysis-ready geometry to traditional CAE solvers.


"Working directly with implicit models for CFD analysis enables us to explore design iterations at unprecedented speed. nTop continues to solve real engineering problems by integrating the tools we need in one cohesive platform."
