Simulation of thin-wall beam

I implemented simulation of thin-wall beam.

The technical detail is explained (in Japanese) in my web page.

FEM for 2D thin-walled beam



The following picture shows non-stationary analysis of falling of thin cantilever beam under the gravity.

In the middle picture, bending stiffness of the beam is 1/10 of top one. And in the bottom one, the bending stiffness is 1/100.
