Fluid defomable surfaces, the influence of surface viscosity in fluid membranes — Veit Krause and •Axel Voigt — Institute of Scientific Computing, Technische Universität Dresden, Germany

We consider a fluid-solid duality of membranes, with in-plane fluid properties and out-of-plane solid (bending) properties. In such systems any tangential flow induces shape deformationas and any change in morphology induces tangential flow. This numerically challanging surface problem is solved by surface finite elements and we explore the dynamics towards equilibrium states in various settings, ranging from transitions from biconcave to dumbell shapes, coarsening of two-component surface fluids under the influence of curvature and wrinkling in fluid membranes.
