The person who contributed this article contacted me by e-mail (e-mail address the same as the website of the externally-linked site) and verified that they are indeed the copyright holder of the text. Accordingly, I have removed the copyvio tag from the article and removed the listing from Wikipedia:Copyright problems. SWAdair | Talk 10:02, 21 Oct 2004 (UTC)

Something that might be useful is pictures of before and after the optimization. That would give people just stumbling on to the subject an idea of what this actually is. I know there are plenty of pictures out there, but I don't know where to find some that are legal to post here. If I get ambitious I'll look around a bit more, or maybe make some of my own. - EndingPop 22 Dec 2005

R3sJAP155M had added a list of tools. That list originally did not cite any secondary sources or in fact any sources beyond the tools' own websites. Now some secondary sources were added. These sources, however, do not meet Wikipedia's standards of reliability; they are user-submitted content without any editorial oversight. One in fact was a mirror of this very article - circular referencing. Thus I agree with the renewed removal of the list. Huon (talk) 20:21, 14 May 2016 (UTC)[reply]

Hello,

So it seems that's you behind the deletion of my work. Can you please tell me what's wrong about this source(pdf) ?

An Integrated Approach to Shape and Topology Optimisation of Mechanical Structures, a thesis by Klaus Fiedler, from Deakin University^[PDF] (chapter 2, page 37 : " a number of commercial software packages are used in the industry e.g. Abaqus [150], ANSA [147], ANSYS [139], CATIA V5 [151], DEP Meshworks Morpher [144], Altair Hypermorph [130], or Pro/ENGINEER [145]"

I also hardly understand why there is such trouble about what I writed. Those software are heavily present in the industry and on the web, a simple Google research has over 16 000 references, and it's a reference without the editor's website. I am kind of new, and not a heavy editor of Wikipedia. I think it's kind of obvious those softwares does exists and are used a lot, I am really impressed by the quality of editing you are asking me. I don't see the point.

Thanks in advance, R3sJAP155M (talk) 21:34, 14 May 2016 (UTC)[reply]

One problem with that reference is that it isn't what you actually cited; thus it's irrelevant to my older comment. A second is that it's not a peer-reviewed scholarly paper but a PhD thesis, technically not subject to editorial oversight. A third is that the list given in that source has little overlap with what was given in the article (though that of course could have been fixed). A final problem - not with the source, but with the article - is that the list basically was a collection of external links to commercial pages, one big invitation for others to add their own spam links to the article. In fact, something like that originally brought me here. Huon (talk) 22:27, 14 May 2016 (UTC)[reply]

There is a page on wikipedia about topological derivative (https://en.m.wikipedia.org/wiki/Topological_derivative). Why we don't link it to the topological derivative section ? Hussein Houdrouge 13:02, 20 June 2018 (UTC) — Preceding unsigned comment added by HusseinHoudrouge (talk • contribs)

The first commercial Topology Optimization product was Optistruct, developed by Altair Engineering and first released in 1994.^[1][2] Topology optimization would later see wide-spread adoption in the engineering analysis software industry.

Adoption Timeline:

• 1994 - Optistruct^[2]
• 2011 - Abaqus 6.11^[3]
• 2017 - ANSYS 18, Fusion 360, Solid Edge ST10, SOLIDWORKS Simulation 2018^[4]
• 2018 - Creo 5.0^[5]
