Re: Topology optimization

Hello shlxx, well I think you are using precompiled version of FreeCAD 0.18 with Python3. In that FreeCAD-Version the module "commands" is not included. Additionally in FreeCAD 0.18 the API has changed a little bit, so that it wont run. This Macro is working for FreeCAD 0.17 precompiled on Python2. ...

Re: Topology optimization

Hello Mark, I will give it a shot. Right at the moment I need to get more familiar with the FreeCAD API, so that the optimization depends on FreeCAD itself and not as a stand alone program. I am working on a Micro-Service based architecture, so that you can switch between GUIS and several other aspe...

Re: Topology optimization

I can speak only according to my project https://github.com/fandaL/beso I don‘t know if someone else is planning to implement topology optimization to FreeCAD (e.g. https://github.com/DMST1990/ToOptiX ) I was thinking already long time ago about making a simple GUI for FreeCAD which would be easier...

Re: Topology optimization

I asked them: "How can i install z88Arion on GNU/Linux". Answer: "It is to much effort to compile it on GNU/Linux." So i think they use some Windows implemented libarys. The Windows-Version works quite well. There is another OpenSource topology optimization software available. Just found http://en.z...

Re: Topology optimization

In most cases like "Solid Thinking" (Altiar) they use a geometric approach. In my case i use Blender for smothing the surfaces with computational geometry methods (Thats the case why i use blender for the post processing). You get a geometric structure with a lot of polygon surfaces. Automatic Polyg...

Re: Topology optimization

Hi, welcome to the FreeCAD forum. It seems good. I put it to my candidate list on which programs to look. ;) I like your tool, its easier to use than mine. :) I have added two pdf- files, which maybe can help you implementing the topology optimization (SIMP, BESO etc...) and understanding the diffe...

Re: Topology optimization

I have written my own optimizer which is open source. (in python) In this case i use calculiX for solving the physical equation. You can optimize any problem and model which run on calculiX. There are different types of optimization: Maximize Heat-Exchange. Maximize Stiffnes. Multi physic topology o...
