    It's amazing how organic the optimal designs look

    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

    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.

    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?

    • @pabloalarcon7905
      @pabloalarcon7905 6 років тому

      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

    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?

    • @Luchsio
      @Luchsio  6 років тому +1

      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.
