Small simulations that run in your browser.

Grab the bracket and pull. The stresses are recalculated every frame with a 2D plane-stress finite-element model: bilinear quad elements, a banded Cholesky solve, and von Mises stress averaged to the nodes.

The arrows behind the page are a vector field; scroll quickly and it picks up. The strips between sections are small transient heat-conduction models; move your cursor along one to heat it. The flow at the very bottom is potential flow around a Joukowski airfoil.
