  1. 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".

  10. 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!
