FreeCAD @CERN

Postby easyw-fc » Wed Jun 26, 2019 10:40 am

Hi, I was curious to find if FreeCAD could be in use by CERN and indeed I found some old student projects:

1) 3D Printing the ATLAS’Barrel Toroid @ CERN Large Hadron Collider (Summer Student Programme 2016)
real Toroid

and the 3D FreeCAD model (designed using FreeCAD, roughly in a scale 1:100 to the real detector)

2) F-watch @CERN (a fully open electronic watch project featuring an integrated GPS receiver)

I forgot to add that the watch was not a simple project, but has been realized :D
Some nice mechanical tips at the slides from Fosdem 2015

maybe we should reach out to CERN especially now that they are transitioning to Open Source? I wonder if they would be open to act as a mirror or even provide CI services ?

If you need someone to go there. I can literally walk to the CERN in less than 15 minutes (depending on which building I need to reach :lol:, it is a very large area). I know some HVAC there guys I have already whispered about FreeCAD but HVAC is probably not the first area FreeCAD will be used in :P .

Edit : I saw mistyped the «not» as I really think there is a long way to go for HVAC domain and so much more interesting use in a site like CERN.

I blog about HVAC / BIM / Energy : pythoncvc.net. If you like you can follow the RSS feed.

'Boots on the ground' literally :)
That's awesome. Well, maybe think of a way to make a presentation and then present it?
Maybe @joel_graff could let us use some of his materials?... since he has done a few presentations about FC already, @yorik as well.

I also would like to consider the tight collaboration between KiCAD and FreeCAD through the Workbench KiCAD StepUp

EDIT:
Moreover before talking to some guys @ KiCAD developer's list, I would like to know @yorik and @wmayer opinion.

I am in the process of developing a GDML workbench see https://github.com/KeithSloan/FreeCAD_Python_GDML

My understanding is that CERN and Jefferson in the USA need to run the designs of their machines through Monte Carlo simulations.
The software for this is ROOT and Geant4, which can take as input a GDML file.

There are challenges taking designs in BRep format ( i.e. STEP) files and performing Monte Carlo simulations on them for reasons I don't really understand, after all FEM uses Mesh etc. The problem is that the simulations just take way too long to run.

There have been attempts to convert to Tessellated GDML file and also an application called McCAD that tries to break down BRep objects into CSG type soiids.

My workbench implements GDML solids ( Much richer set than FreeCAD csg) as FreeCAD Python Objects and as a result one can change
the values by editing the properties which are the same as defined by the GDML specification/manual.

Anyway to date my workbench repository has received 4 stars and 2 thumbs up in the Geant4 forum. but none of these people work for CERN.

One of the test files in my repository is lhcbvelo.gdml which I assume came from CERN. I would be very interested to test with others.

I am under the impression that CATIA has some facilities for creating GDML, but as CATIA is very expensive and not open source, I don't know much more about it. SolidWorks may also have similar facilities.

I think one of the reasons behind their Open Source effort was Microsoft jacking up the license fee's not sure other vendors have
followed suit to the same extent.

Cern moved toward OpenSource with KiCad because they needed a unified platform to develop and share PCBs around their different labs and locations...
Printed Circuit Boards (PCB) are the heart of any electronic device, from toasters to smartphones. But so far, the engineers who design the boards often have had no option but to use proprietary tools. That's about to change: CERN experts are adapting the open-source software KiCad to make it an efficient tool for designing open-source hardware. This free software makes it easier for electronics engineers to share their designs.
