Diffusion redistanciation schemes for higher order geometric motion and application to red blood cells

Description
In this talk we will present a new way to compute steady state solutions to the Willmore problem using a diffusion scheme on a distance function coupled with a redistanciation step following Esedoglu et al. (2010), where we added an area and volume constraints. In this approach, a complex nonlinear flow could be approximated by a combination of diffusion equations. This could be used as an efficient  predictor step for the full fluid-structure coupling problem.
