👋🇮🇹 We’re back from the ECCOMAS Advanced Course NL26 on Nonlinear Computational Solid & Structural Mechanics in Pavia.

📚👨‍🏫💻The week offered an intensive and well-structured deep dive into numerical techniques, solution algorithms, and finite element approaches for nonlinear solid and structural mechanics. Across lectures and tutorial sessions, the course created a strong setting for discussing both fundamental concepts and current research directions in nonlinear computational mechanics.
👨‍👩‍👦‍👦 Our institute was represented by Manfred Bischoff as one of the lecturers, and by several of our doctoral researchers who attended the course as participants.

🙏 Many thanks to Ferdinando Auricchio, Manfred Bischoff, Carlo Lovadina, Guillermo Lorenzo Gómez, Robert L. Taylor, and Peter Wriggers for the excellent programme and for sharing their expertise.
It was a valuable week of learning, discussion, and scientific exchange in Pavia.

In #FElupe, a #python package of mine, I changed the API of a function: the output included two return variables (boundaries, loadcase), where the second one is nowadays mostly unused. So I added a new argument return_loadcase=None, which does not change the return behavior, but marked as deprecated. In a future major version, return_loadcase will be False by default. Now all users have at least one major version time to update existing scripts. Is this good practise or could this be improved?

If one has a linear-elastic material in mind, one would assume this works for any kind of finite element simulations. In case of large rotations and large strains, "linear" is not unique. There are many different implementations of linear-elastic materials. Beside the mathematical details, a cube, rotated by 90° and stretched to a factor of 2, will show different deformations. You'll see a small-strain, Total-Lagrange (Saint-Venant Kirchhoff material) and the co-rotated framework as well as a compressible Neo-Hookean material model formulation.

Reminder: don't use small-strain linear-elastic material formulations in simulations where large rotations occur - just because the strains are "small".

All figures created by #felupe for simulation and #pyvista for plotting.

I made a #streamlit app for a nonlinear #fea simulation of a deformable hyperelastic solid body. This uses #FElupe for the simulation and #pyvista / #stpyvista for showing the final result in your browser.

What do you think, which #logo is better? It's for an open source FEA #python package.

Logo A (round) or B (square with rounded corners)? Here's the poll: https://mathstodon.xyz/@adtzlr/115153260402286236

After a summerbreak, #FElupe development continues! Stay tuned for lots of handy new features: checkpoint/restore, revolve a.k.a. axi-to-3d, simplified handling of multiple solid bodies, etc. These new features are already available in the main git branch and will be released soon.

P.S. I'm always open for new ideas, just let me know!
