I am interested to hear what peoples thoughts are on Topology Optimisation. Is it something that people are aware of?
Please do let me know your thoughts and opinions
There is a thread somewhere around here by a DSS person looking for feedback. You might search for that.

Just wondering it's something you want to do or what you do for your job now?
Thank you for your responses, optimisation is the heart of the company I work for and with optimisation growing with more and more people using it daily, I wanted to know how much the users of SolidWorks know about optimisation and the general feeling towards using optimisation in daily designs.
I think it's in mind of most consumer product designers today as a way to cut cost and make the products more competitive
SW provides tools which can be used for eng. analysis while power surface (3rd party addin) is also a good tool for this purpose
Yes, I agree. The use of Topology Optimisation is a great way for designers to cut the material costs without compromising on the strength of the part. However, are designers really aware of the full capabilities and using it on all designs instead of just when they need to make a particular part lighter to meet budgets?
To be competitive on the tough market today, most companies (except Apple ) keep dropping the price tag on their products while the labor cost is up - Does that answer your question? I don't think it's a last minute call for most designers as I've heard over and over before we even start a new project
Yes, I must be very difficult to compete on price and I am glad to hear that optimisation is becoming an integral part of the design process. My next question would be, what system is being used to do this optimisation when using SolidWorks? Are designers using an external software and then importing it back into SolidWorks? Or just using the basic Simulation Package available with SolidWorks Premium?
I believe SW provides enough tools for this task (depend much on your industry) - SW premium (mine is premium ) only includes light version of the eng. analysis such as FEA while you can purchase (extra $$$) complete packages - 3rd party package such as Power Surfacing (I have it too ) is a "plus" to make your job more easier
yes, my understanding is that the optimisation available in SolidWorks, without paying for an add in has limited capabilities. There are add-ins available that allow designers to optimise within the SolidWorks interface, such as TruForm SW, which eliminates the step of going to another software.
A tool such as this is aimed at cutting down the design time, and making a designers day to day easier. Is this something that the market needs, or are there enough tools available and easily accessible?
Is this a sales pitch?
Merely a conversation to find out the understanding of Topology Optimisation in SolidWorks users and providing information about a product that might make a designers job easier that they may be currently unaware of. Apologies if you find this conversation too sales pitchy!
there is topology optimization in autodesk which is called shape genrator in autodesk nastran incad but i don not know if this is present in nastran incad for solidworks
If you utilize the 'Design Insight' feature SW will highlight the load flow path (for those who have difficulty visualizing it or have not had engineering classes where it used to be taught - yes, I'm old). Anywhere there isn't color you don't need material is the simplistic interpretation.
Altair Optistruct is a fairly powerful tool but they also have a more 'designer-friendly' package called Inspire. Unfortunately, because people are still just people, there is a bias against "flimsy-looking" designs so designers end up putting 4 bolts where one would do, etc.
We have come across a very similar feeling towards 'flimsy looking' designs. Something that TruForm SW does is provide the optimisation results and allow the designer to draw around it there and then, enabling the 'flimsy' areas to be padded out a bit. It must be frustrating as the designer to have to redesign things because humans do not trust what it looks like. As designers do you always trust the optimisation?
Haha, I am also unsure about the availability of Nastran incad for SolidWorks but I will certainly be looking into it.
I'm not a designer, I'm an engineer. Personally, I do not believe it is any wiser today than it was 10-15 years ago to put 'tools' in the hands of those without the background and education to realize the limitations of such. BTW, Inspire does the same thing and so does OptiStruct but at a more robust level.
what do you mean by this sir, Those who are not engineer are not able to understand the limitation of the software?
I thought I was rather plain but I will clarify for you. Designers usually do not have at least a bachelor degree yet many call themselves engineers. FEA (and all the related software) is better left to those with great experience and education. I've seen too many FEAs here and other places where the software is used incorrectly and unrealistically leading to a false sense of security. Of course I have also run into many 'engineers' (with degrees) who, likewise, do not have the understanding of the correct uses and interpretation of the results.
that's make its better, I agree with to you sir, but i seen also a guy that its not an engineer but his pretty damn good will of course considering his years of experience and so many books in his table.
