Teaser

It occurred to me that simply dropping a post about some basic math that we’ve all either already known about (and perhaps forgotten) is probably not the best way to get your attention and keep you wanting to come back here. As I hope to have at least one new blog post up every week (with a mix of current and past work, theory and practice, history and philosophy, etc.) I certainly hope this site will make you want to come back at least weekly.

But to try to, well, sweeten the deal a bit, I wanted to drop a little hint about some of the work I expect to be highlighting here over the next couple of weeks. My principal focus (aside from my day job) has been in aggressively learning the capabilities of code_aster and salome_meca. I’ve been using these tools off-and-on for the better part of 4-years ever since stumbling across CAELinux back then (by the way version CAELinux 2020 is available now!) But I never really moved-on past the basics.

Well with the help of some online tutorials (especially grateful to Cyprien for these, in particular) and after pouring through the someone hilarious to read (because of the machine translation from the original French) documentation for code_aster, as well as finally gaining sufficient confidence in my basic CAD skills (with commercial tools) to give FreeCAD a go, I think I may have finally achieved sufficient competence that I may have a few stories to tell.

So starting with some geometry built in salome_meca and FreeCAD…

A simple “complex” part from FreeCAD – for future work

… I’ve been able to do some pretty interesting studies in the areas of nonlinear static analysis as well as contact. For example…

An even-more simple “complex” part with contact, analyzed in code_aster with salome_meca

My next steps are to expand these studies to include material nonlinearity, further analyses of contact, and coupled-thermal stress analysis. But for now, let me just leave you with a brief note on my benchmarking work with salome_meca. Enjoy!
