A Stream-Function Formulation for the Surface Stokes-Helfrich Model - Surface Finite Element Discretization and Validation
Enno Igel, Maik Porrmann, Axel Voigt
We introduce a stream-function formulation for the Surface Stokes-Helfrich model and study an Arbitrary Lagrangian-Eulerian (ALE) Surface Finite Element (SFEM) discretization in sp…
Surface Minkowski tensors to characterize shapes on curved surfaces
Lea Happel, Hanne Hardering, Simon Praetorius +1
We introduce surface Minkowski tensors to characterize rotational symmetries of shapes embedded in curved surfaces. The definition is based on a modified vector transport of the sh…
Suppression of hyperuniformity in hydrodynamic scalar active field theories
Nadia Bihari Padhan, Axel Voigt
The coarsening dynamics at late times in phase-separating systems lead to universally hyperuniform patterns. This is well known for scalar field theories, such as the Cahn-Hilliard…
Shape Evolution of Fluid Deformable Surfaces under Active Geometric Forces
Maik Porrmann, Axel Voigt
Models for fluid deformable surfaces provide valid theories to describe the dynamics of thin fluidic sheets of soft materials. To use such models in morphogenesis and development r…
Flow Through Porous Media at the Percolation Transition
Mirko Residori, Suvendu Mandal, Axel Voigt +1
We study low-Reynolds-number fluid flow through a two-dimensional porous medium modeled as a Lorentz gas. Using extensive finite element simulations we fully resolve the flow field…
From cell intercalation to flow, the importance of T1 transitions
Harish P. Jain, Axel Voigt, Luiza Angheluta
Within the context of epithelial monolayers, T1 transitions, also known as cell-intercalations, are topological rearrangements of cells that contribute to fluidity of the epithelia…
Wrinkling of fluid deformable surfaces
Veit Krause, Axel Voigt
Wrinkling instabilities of thin elastic sheets can be used to generate periodic structures over a wide range of length scales. Viscosity of the thin elastic sheet or its surroundin…
Active smectics on a sphere
Michael Nestler, Simon Praetorius, Zhi-Feng Huang +2
The dynamics of active smectic liquid crystals confined on a spherical surface is explored through an active phase field crystal model. Starting from an initially randomly perturbe…
