FAQ on Topology Optimization

What is Topology Optimization Software?

Topology optimization software is a package that applies simulation-driven techniques to minimize material usage. By removing material from areas that do not carry significant loads, a part is generated that meets design objectives (like weight reduction) while fulfilling design requirements (such as available materials or manufacturing constraints).

How does topology optimization work?

We have put together in our topology optimization guide on how to get the most out of topology optimization in engineering design. If the guide does not answer all of your questions, you can also book a demo with us and find out which modeling pain points nTopology will solve for you!

What is Topology Optimization Software Used For?

Topology optimization software is used to improve structural performance and generate lightweight alternatives to dense designs. Today, topology optimization is mainly used in aerospace and automotive applications to reduce the weight of advanced engineering products and improve their performance and efficiency. However, topology optimization also finds applications in the medical, industrial, and consumer product sectors where lightweighting is important.

What topology optimization objectives & constraints are available?

nTopology gives you complete control of the topology optimization process. It allows you to optimize for a single or multiple design objectives, including structural compliance to specified loads, volume fraction, and displacement. The available geometric constraints include planar symmetry, extrusion, overhang, and more. You define materials with custom properties or select from a list of presets.

How can I verify topology optimization results?

nTopology’s built-in simulation capabilities enable you to create integrated topology optimization verification processes. nTopology also streamlines the export of simulation meshes for FEA or CFD analysis in external simulation tools and integrates with multidisciplinary design optimization tools.

Can I export topology optimized parts from nTopology to my native CAD system?

Yes. nTopology allows you to export topology optimized parts in the STEP or Parasolid file format to your CAD system for downstream design operation. See full data import and export capabilities.

Can I import topology optimization results to nTopology from 3rd party software?

Yes. nTopology supports the import of raw topology optimization results from popular 3rd party software. Many users take advantage of this capability to accelerate their design processes using nTopology’s automated geometry reconstruction and advanced post-processing capabilities.
