Convergence of a scheme for elastic flow with tangential mesh movement
Paola Pozzi, Björn Stinner
Elastic flow for closed curves can involve significant deformations. Mesh-based approximation schemes require tangentially redistributing vertices for long-time computations. We pr…

A surface finite element method for computational modelling of cell blebbing
Björn Stinner, Andreas Dedner, Adam Nixon
Cell blebs are protrusions of the cell membrane and can be instrumental for cell migration. We derive a continuum model for the mechanical and geometrical aspects of the onset of b…

A converging finite element scheme for motion by curvature of a network with a triple junction
Paola Pozzi, Björn Stinner
A new semi-discrete finite element scheme for the evolution of three parametrized curves by curvature flow that are connected by a triple junction is presented and analyzed. In thi…
