Playing with #FiniteElementAnalysis of an "expansion mesh" like structure. The geometry, mesh and boundary condition creation, as well as the FEA analysis, all occur automatically.

This simulation is still elastic, next step is to add plasticity.

Interesting paper by @jedbrown et al.

For computational mechanics/physics, if you code by just punching in the equations from the textbooks directly, the physics should work, but computationally the way you evaluate the quantities may be unstable. This paper lists some recipes to avoid these.

Mostly small strain problem, but still feels icky to leave in.

Just a bit of #julialang looking ridiculously awesome :)

Checking out "Taubin" smoothing. Looks great for smoothing voxel derived meshes. Video shows voxel mesh (red) of a femur and the Taubin smoothed surface retrieved (white).

One of Taubin's papers: https://doi.org/10.1109/ICCV.1995.466848
