Re: FreeCAD as pre-post processor for MBDyn
Hello, I am interested in using MBDyn with FreeCAD. I have try some years ago a similar module in Comsol. If I remember well, it has an extra cost in term of memory and time to be able to calculate the constraints in bodies with the dynamic module (elastic bodies). When computing only displacement,...

Re: FreeCAD as pre-post processor for MBDyn
Hello, I was wondering if this post processor allows the export to Matlab of the results obtained from the simulation. The original software, MBDyn, has this function, which is why I was wondering if this feature was also provided in this post processor. I also wondered if it would be possible to e...

Re: Assembly 4 workbench
hopefully you are still checking for an answer Sure I am checking - both for answer and new posts. Thank you for your answer. I like an idea of defining moving parts in sketch, like in Mads' tutorial with hexapod https://www.youtube.com/watch?v=i9uY9dXGJA8 But I think it is possible only when all p...

Re: FreeCAD as pre-post processor for MBDyn
I have written a tutorial on how to simulate a slide crank as done in the sky engineering tutorial below. https://www.sky-engin.jp/en/MBDynTutorial/chap17/chap17.html I hope it helps. The tutorial is in the WB's repository wiki; linked below. https://github.com/mfasano727/MBDynFCwb/wiki/Slide-Crank-...

Re: FreeCAD as pre-post processor for MBDyn
I have the joints for that example. I will need the force and plugin variables.carno wrote: ↑Sat Nov 07, 2020 4:40 am I want to try following tutorial.

Re: FreeCAD as pre-post processor for MBDyn
I have fixed the inline joint offset bug(commit 160). I will be working on the tutorial for the slide crank mechanism. I will let you know when I am done with that.

Re: FreeCAD as pre-post processor for MBDyn
I want to realize the following tutorial, but there are missing node types: abstract, dummy; the joint types: in plane, revolute rotation; element types: genel, force. I am also not clear how to create reference surfaces or lines which coincide with the geometry. What can I do for this please? Than...

Re: FreeCAD as pre-post processor for MBDyn
Okay, I will try new commit. Another feedback is, it is putting a word 'offset' in the 'In-line Joint' script. This seems to be a syntax error. Let me know if I am wrong. joint: 3, in line, 3, position, null, orientation, , 0.0, 0.0, 0.0, 2, offset, 0.0, 0.0, -3.0; There is a bug with the offset fo...

Re: FreeCAD as pre-post processor for MBDyn
I made a mistake with the gravity units conversion It is fixed with commit 158.
To change the simulations parameters right click the simulation and select edit in the popup menu.

Re: FreeCAD as pre-post processor for MBDyn
Hi, I am trying to run the pendulum tutorial. Earlier WB was not running the simulations, which seems to be solved. I am facing two problems. 1. I am not able to add gravity. It is just adding blank entry. It is giving me following error. I made changes that I think will work(commit 153). I will no...
