A numerical approach for fluid deformable surfaces
Sebastian Reuther, Ingo Nitschke, Axel Voigt
Fluid deformable surfaces show a solid-fluid duality which establishes a tight interplay between tangential flow and surface deformation. We derive the governing equations as a thi…
Defects in active nematics: algorithms for identification and tracking
Dennis Wenzel, Michael Nestler, Sebastian Reuther +2
The growing interest in active nematics and the emerging evidence of the relevance of topological defects in biology asks for reliable data analysis tools to identify, classify and…
Liquid Crystals on Deformable Surfaces
Ingo Nitschke, Sebastian Reuther, Axel Voigt
Liquid crystals with molecules constrained to the tangent bundle of a curved surface show interesting phenomena resulting from the tight coupling of the elastic and bulk free energ…
Comment on Geometrical Control of Active Turbulence in Curved Topographies
Ingo Nitschke, Sebastian Reuther, Axel Voigt
In the recent letter Pearce et. al. Phys. Rev. Lett. 122, 168002 (2019) the authors investigate the turbulent dynamics of a two-dimensional active nematic liquid crystal which is c…
Hydrodynamic interactions in polar liquid crystals on evolving surfaces
Ingo Nitschke, Sebastian Reuther, Axel Voigt
We consider the derivation and numerical solution of the flow of passive and active polar liquid crystals, whose molecular orientation is subjected to a tangential anchoring on an…
Solving the incompressible surface Navier-Stokes equation by surface finite elements
Sebastian Reuther, Axel Voigt
We consider a numerical approach for the incompressible surface Navier-Stokes equation on surfaces with arbitrary genus . The approach is based on a reformulation o…
Discrete exterior calculus (DEC) for the surface Navier-Stokes equation
Ingo Nitschke, Sebastian Reuther, Axel Voigt
We consider a numerical approach for the incompressible surface Navier-Stokes equation. The approach is based on the covariant form and uses discrete exterior calculus (DEC) in spa…
The interplay of curvature and vortices in flow on curved surfaces
Sebastian Reuther, Axel Voigt
Incompressible fluids on curved surfaces are considered with respect to the interplay between topology, geometry and fluid properties using a surface vorticity-stream function form…
