Absolutely fantastic stuff. Thank you! I'm looking to use this in optimizing a chassis for my 3d printed robot. Do you think it is possible to use this software to do such? What are the more advanced applications you've done? Thank you again!
Great introduction to topology optimization! Could you clarify how you arrived at the thermally optimized cylindrical structure at 0:18 (assumptions, boundary conditions, load case, etc.)? In my bachelor thesis, I am comparing parametric thermal optimization with topological (thermal) optimization. I'm quite new to topology optimization, so It would be great to have a place to start. Thanks in advance.
So it was a 2D optimization which was extruded repeated and Rotation along the pipe axis. The Ring of the pipe was Applied with a Constantant temperature. The Design Domain was Applied with Constant heat flux. I hope that kinda helps you.

Hi! VoxelBeaver. My name is Yiheng, from China. I was pretty impressed by the case of honeycomb sandwich plate in your video. It finally changed the size of the core. Could you please give a detailed explanation of it? Also, could you give us your e-mail if convenient. Thank you all the way!
Hi I cannot seem to get the ToOptix to work in Blender as I keep getting a error when I try to enable it. Would you please be able to help me please? It seems to complain about .py files ????
Hi Angelo, sorry for the late reply. The optimization for the blender version was only available for Blender 2.80 alpha. You can use in contrast to the blender version the plane python Version github.com/Foxelmanian/ToOptixCore which is quite stable. As an alternative I would suggest the topology optimization in FreeCAD github.com/fandaL/beso . The API of Blender and FreeCAD changes a lot. Therefore updating the Addons is quite a mess. The core version works therefore way better. If you need further assistant, we can switch to Discord/Zoom if you wish
Your right. This video is just an overview. It is explained in some other videos :). In part 2 the sensitiviy analysis is visualized and expalined. Part 1 ruclips.net/video/_erS8dRxILM/видео.html Part 2 ruclips.net/video/DLE9qt07ck0/видео.html Part 3 ruclips.net/video/xmwRilc6xdc/видео.html
Thank you for your informative video. Is there any way I can have an example Matlab code or CAE Software example for such topology optimisation problem?
Hello Mr. Zolfagharian, for 3D-Cases in heat transfer and static load cases you can use the open source software (Acces by Python or Blender UI) : github.com/DMST1990/ToOptiX For a simple 2D-Case and the understanding of topology optimization you can use a 99 line matlab code (only static load cases): www.topopt.mek.dtu.dk/Apps-and-software/A-99-line-topology-optimization-code-written-in-MATLAB For fluid mechanics you need to use comerical software like Abaqus (Tosca)
Thanks heaps DMST for your prompt reply. I have been working on 3 printed soft actuators as my Ph.D. thesis. We have already managed to publish some good paper in this area, and now I am wondering to incorporate topology optimization into the field. That should not be too time-consuming to marry between these two concepts for publication purpose. It would be my pleasure to have your consent for further collaboration on this and have joint publication. please let us be in contact via this email, azolfa@deakin.edu.au , if you are happy with.
Hello, I am a novice, now i am need an expert guidance, if there is a video on the topological optimization of teaching examples is better,Looking forward to your reply.thank you!
The Tooptix software is an opensource code? I'm looking for a software where can I develop a multi-physic optimization considering electro-chemical reactions, fluid mechanics and topology optimization in a porous material. Would it be possible for me to implement something like that in the software?
We can talk about it, because the model that I need to develop is highly multi-physic and coupled, because it is intended to partially fulfill the requirements of a PhD thesis

It's amazing how organic the optimal designs look
And the best of it You can find such structures in the nature like the wings of a fly
DMST Those were my thoughts when I saw the “bridges” that were optimized
@@FrappuccinoAlfredo Hi Domino, take a look at the Plant "Santa Cruz Seerose" espeaccially the back of the see roes :). This looks quite incredable

DMST 1990 thank you
very interesting
Amazing! Thank you!
Thanks, it is very helpful!
Sir u r just brilliant, please share u r knowledge of open source topo optim with salome or.. Like that thaks for every thing...
Thanks, the Code for the optimization is already available on github as an open source project. Unfortunately small knowledge in python is reqiered.
hi and thanks for your helpful video. please share more videos for topology optimization
Hi,
no problem.
Do you need some theoretical back ground or some explenations of how to use applications?
Yes please do more videos about theoritical background
for exmaple how to choose which type of optimze is propper
@@KasunGayashan_2012 all right I will create some new one, sorry for the late responde. I missed that comment.
maybe also some example on how the new Tooptix release works with freecad and blender since I have some problems to install it @@Luchsio

Ah sorry i missed that only heat conduction was assumed, so no convection...
@@Luchsio Thanks for your fast response! I will take a look at it.

Hi, Yiheng unfortunately i did not get any Mail.
Seems like a similar process to how a slime mold optimizes its structures.

Quite interesting. Thanks. Any example with COMSOL?
On Acculution.com I show examples for acoustic topology optimization using COMSOL.
the sensitivity analysis is the most important part, and you don't want to go into detail? :D
Your right. This video is just an overview.
It is explained in some other videos :). In part 2 the sensitiviy analysis is visualized and expalined.

Hi Pablo are you still working on RUclips phd
You sound like military history visualized
well i dont know how military history sounds like 🙂.
