nTop delivers unprecedented flexibility and control over geometry, but meshing can become a bottleneck when it’s time for analysis. Intact.Simulation directly loads nTop implicit files without any loss of fidelity, solving the implicit geometry without the challenges introduced by meshing.
Features for nTop customers:
- Physics: Linear Elastic and Thermal, (Modal coming soon!).
- Supports implicit, mesh, curve, and voxel geometry, with toolpath support planned.
- Ideal for complex bonded assemblies and materials like mixed topology lattices, foams, and surface grids.
- Includes fast linear solving for concept design and precise quadratic solving for validation.
- Compatible with industry-standard visualization and validation tools.
Benefits:
- Quickly iterate on implicit designs and detailed lattices without translation, meshing, or simplification.
- No need to compromise performance versus fidelity on mission-critical geometry.
- Handles complexity impossible with traditional FEA.
FAQs
How does nTop integrate with Intact.Simulation?
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!
How do I acquire the integration?
Intact.Simulation is required to be licensed through Intact Solutions and installed for the integration. Intact Solutions will provide nTop custom blocks and examples for the integrated workflow.
How does Intact.Simulation complement nTop’s FEA tools?
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.
