Abstract

Focussing on models of springy wires, we study framed curves whose evolution is driven both by the bending energy and the twisting energy. The latter tracks the rotation of the frame about the centerline of the curve. In order to prevent topology changes during the evolution, we add a self‐avoiding term, namely the tangent‐point energy. We discuss the discretization of this model and present some numerical simulations. This is joint work with Sören Bartels.
