Welcome to Topology-Opt.com

We review topology optimization related applications, research and software in this website.

Due to the immense amount (thousands per day) of spam comments incoming, we cannot read all comments and resort to deleting them all. I hope spammers will give up at one point.

Topology Optimization for Morphing Micro Air Vehicles

In this interesting thesis study (link) James R. Elgersma explores the Morphing Micro Air Vehicle wing optimization for various morphed shapes and loads. Also actual Matlab code is presented at the end of the text. Interesting structures resembling insect wings veins structures appear for some load configurations.

Unmanned Helicopter Optimization

This Unmanned Helicopter optimization by CompoLight is a very nice example of how topology optimization can be applied. There is not much detail about the work, but this picture alone is satisfying.

Lotus Vehicle Mass reduction study

These documents (link 1 , link 2) by Lotus which is a continuation of a study we previously featured. There are remarkable weight savings but these are mostly due to usage of light wieght materials. How the topology optimization results are incorporated into the design is still not clear, bar a few minute details.

Who can benefit from Topology Optimization?

We are reviewing lots of articles and other materials, however someone new to the area may not see in which industries can benefit from topology optimization. So we decided to write a short article on this. So if you are a professional skip this article.

What springs to mind when one hears topology optimization is the minimum compliance type. In this type, we specify a volume and certain constraints and forces in the topology optimization software, and it shows us a (nearly) optimum structure which will have the least compliance with the given weight. Minimum compliance implies maximum stiffness. And maximum stiffness is important in many many applications. Maximum stiffness with minimum weight is even more important. It is usually easy to achieve high stiffness even without any simulations, however doing it while constraining weight is hard. And topology optimization excels here. And the resulting structure is generally good in a strength point of view too, as all the structure is loaded efficiently.

So who can use it? The answer is basically anyone that deals with load bearing structures. Its usage in automotive is well known. We have covered its usages in Industrial machinary, buildings, aircraft, ships, wind turbines, medical implants, armor, composites… Anything that has to endure loads can be made better.

If you are not sure how you can use topology optimization, feel free to contact us.

There are other variants of topology optimization. They are not used as frequently. One is compliant mechanism design. In this type we specify some input and output movement and ask the software to find which kind of  structure will satisfy it. For example we want a chair that raises the head rest when someone sits on it, without any hinges etc. So it will deform elastically to give the results that we seek. There are various academic examples, however practical usage is close to none.

Another type is in which CFD is coupled with topology optimization to give some desired results. It is rather flexible (flexibility probably depending on the skills of coder). So one can use it to produce low friction, directional flow (high resistance in one direction low in the other), to give uniform flow, uniform pressure distribution etc. probably limited by the imagination of the user. This type is gaining popularity in related industries. However it is computationally very intensive.

Another type is heat flow optimization. Users can optimize structures that will create highest heat flow. We are not knowledgable in this are so its up to the reader to research if interested.

As you can see there are various types of topology optimization (some not covered). Probably any industrial company can benefit in one form or another.

ManufSim development build released

Here is our free for all 2D manufacturing game/simulation Manufsim link. (Requires Unity 3D webplayer, which is a nice and popular 3D tool) Please share the link with the people that may benefit from this software, such as students.

Please watch the linked video before opening ManufSim: ManufSim intro video.

It is still in development phase, and is rather unpolished. We want to keep it free and thus we are searching for sponsors. If you are interested please send an e-mail to:

Topology Optimization of Vehicle Body Structure for improved Ride & Handling

In this rather long text (seems to be a thesis) by Emil Norberg and Sebastian Lövgren of Liköpings University (link), a vehicles front structure is being optimized. We could not read it so far, however a quick skimming reveals that different parameters and meanings of different results and techniqes were discussed, which is a much needed thing in this area. Seems to be a interesting work.

Optimization of Tesla valve

In this article (link) the No-Moving-Parts valve inspired from the Tesla valve is topology optimized with coupled fluid dynamics. It is a very clever piece of design from the amazing Nikola Tesla that allows easy flow of fluids in one direction but impedes their motion in the other direction, and without any  moving parts. Sen Lin from Chinese Academy of Sciences has taken Tesla’s invention and took it one step forward by optimizing it. We hope there can be some applications someday.
