Solve complex models directly on nTop geometry. No body-fitted FE mesh to build or repair
Skip defeaturing and model cleanup. Analyze the real geometry, lattices and all, at the fidelity you choose.
Intact reads nTop's .implicit file directly. No export, no conversion. The same geometry drives design and analysis.
Setups are reusable and geometry-driven. Swap one design for the next and re-solve without rebuilding the analysis model.
Intact runs as native nTop blocks – Stress, Modal, Thermal, Thermo-mechanical, and Preview. Define studies, launch simulations, and visualize results right in nTop, at full fidelity throughout.
Fluid pressure transferred straight onto the implicit model - no meshing - for aeroelastic response on a full airframe.
Steady-state thermal across a lattice heat exchanger, solved directly on the implicit geometry.
Structural stress on a dense Isogrid - every strut solves directly, no meshing.
Uniform vs. field-driven varying-thickness lattices under one load case. Quantified: up to 20% lighter at comparable stress and displacement.
Intact.Simulation is integrated into nTop using custom blocks that allows the user to set-up, run, and post-process the results without leaving the nTop environment. After installing Intact, you can access it via the nTop Connectors tab.
Structural, thermal, modal, and thermo-mechanical analyses on nTop’s .implicit geometries. Anisotropic and multi-material assemblies are also supported. See documentation for full capabilities.
Yes! Fluid pressure maps straight onto the implicit model without meshing, enabling aeroelastic and FSI simulation on complex, full-scale geometry. See the docs for the current supported list.

For over half a century, the finite element method has dominated structural engineering analysis. nTop’s traditional FE solvers are best-in-class, providing referenceable results that are highly compatible with upstream and downstream FE tools. However, traditionally FE methods don’t scale well as the complexity of geometry increases, because traditional FEA requires high-quality, body-fitted meshes which may be challenging or impossible to generate on complex geometry.
Intact.Simulation works off of nTop’s both native implicit geometry and explicit geometry such as meshes. Intact.Simulation enables both fast conceptual simulation using coarse linear methods as well as high-fidelity analysis using quadratic elements on a fine grid. In particular, Intact.Simulation can approximate performance of periodic geometry, such as lattices, at any resolution, from fine fully resolved details to coarse resolutions with effectively homogenized behavior.
Intact.Simulation’s boundary conditions are specified geometrically instead of topologically, which makes it easy to swap out different geometry models in the same test harness, validating performance throughout a product or design’s lifecycle.
Why implicit models have been hard to simulate, and how Intact closes the gap.
No conversion, no repair, no mesh.
