open source

Dear mechanics community,

I would like to draw your attention to our recent publication about the opensource finite element framework GetFEM:

https://dl.acm.org/doi/10.1145/3412849

I am currently looking to hire a postdoc to work on DEM modeling of dynamic problems and impact events. The ideal candidate will have strong programming skills (C++/Python) and existing experience with open source software and GUI development. Full details may be found at this link. The announcement lists a start date of September 1, but this is flexible.

Folks,

I'm embarking on a project to build a modified copy of a DIY 3D printer.  See http://reprap.org/wiki/WebHome to get a rough idea.  In my case, I have my own lathe and milling machine, so I can fabricate more substantial components, e.g., by machining aluminum.  I also have larger stepper motors, some 3/8" precision rod and linear bearings that I can use. 

Summary:

I am thinking of informally conducting a specific case-study concerning the FEA solvers. The reference problem is a very simple but typical problem from stress analysis, leading of course to the linear systems: Ax = b and Ax = Lx.

I seek advice as to what software libraries currently available in the public domain would be best to use---the ones that would be fastest in terms of execution time for the reference problem.

I have a personal and longer-term research interest with certain issues related to the solvers technologies.

I will be setting up an open source project for parallel finite element analysis in the next month or two. I am just wondering what the community's opinion is regarding the best repository to use.

SourceForge? Google Software? Others?

Your opinions are welcome.

A new AP article appeared today on  free access to college's educational materials, particularly spot-lighting the MIT Open Course Ware initiative.   Also discussed are available educational materials through iTunes and Youtube.   iMechanica has also got a growing repository of course notes on mechanics topics. 

Update: An Open Source Review page has been created. Please feel free to leave links, codes and comments on the page. 

Dear Mechanicians,

I have seen that there is lot of code sharing among the mechanicians at iMechanica; a search for the word "code" for example produces nearly fifty entries, of which, I believe, at least half of the posts are pointers to codes and their sharing.
