A finite element approach for vector-and tensor-valued surface PDEs

M Nestler, I Nitschke, A Voigt - Journal of Computational Physics, 2019 - Elsevier
We derive a Cartesian componentwise description of the covariant derivative of tangential
tensor fields of any degree on Riemannian manifolds. This allows to reformulate any vector …

Hydrodynamic interactions in polar liquid crystals on evolving surfaces

I Nitschke, S Reuther, A Voigt - Physical Review Fluids, 2019 - APS
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 …

A tangential and penalty-free finite element method for the surface Stokes problem

A Demlow, M Neilan - SIAM Journal on Numerical Analysis, 2024 - SIAM
Surface Stokes and Navier–Stokes equations are used to model fluid flow on surfaces. They
have attracted significant recent attention in the numerical analysis literature because …
