The longer I think about about this problem, the things get stranger.. bugae, the coordination-system in your post (I do a repost here) appears by doubleclicking on an object in the model tree. It is a transformation tool. Very useful to move objects. But we wont move the mesh. Again: try to "i...

Are you kind enough to tell me what I should write on CMD please? Sorry, I run windows, no experience with Ubuntu. Keep in mind that the cfd-of wb is based on bluecfd-core, an openfoam clone for windows. http://bluecfd.github.io/Core/Downloads/ If you have problems with installing openfoam/cfd-of u...

Hi bugae, welcome to the Freecad-forum. For cfd you should use the latest FC0.18 development snapshot: https://github.com/FreeCAD/FreeCAD/releases How to install and first run cfd-of workbench: https://www.youtube.com/watch?v=8A9GewANqh8 openfoam-basics: https://www.youtube.com/channel/UCjdgpuxuAxH9...

@Oliver I think we need a tool to define a box for phases i.e. water / atmosphere including the material properties of each phase and an automatic refinement of the boundary of the phases. As Oliver said: I initialize the complete field with zero water fraction, then later the initialization zone (...

Ok, a little calculation.
Bernd/Uwe, can you tell me which part of the model tree I can export to vtk-format?
I still use the the frd-to-vtk-tool from user mamah.

First of all I would like to thank the developers of the 0.18 version of FreeCAD, I truly feel that this is a version which is not only usable for real world engineering projects but also a competitor for some of the high dollar commercial CAD packages. Sir, you make my day :) Cool project. BTW: yo...

In my understanding if this system is to fail anywhere in the plywood construction it will be at the node "fins" (the curved bits) that have loads in tension. That is why I think I need the FEM analysis. The calculation of the complete node is tricky, it is a contact problem. You can run ...

Just a retired construction worker with an idea that has been spinning round in my head for many years. Any help would be greatly appreciated. You are welcome, Freecad makes ideas working... For a structure like yours (spaceframe) there should only be normal-forces (force along beam axis), no bendi...

Hi johno,
willkommen in FC-Forum. Dein Dach kann mit einem
Grundkörper und einer Operation (wedge-Körper + thickness-tool)
in der part-wb erstellt werden. Oder willst du die Rahmenprofile zeichnen?

Hi Laurie,
I had a look at your model. Great job!
For a static analysis it is better to use a 3D-frame (beam-elements).
Something like this:
