A divergence-conforming finite element method for the surface Stokes equation

Abstract: The Stokes equation posed on surfaces is important in some physical models, but its numerical solution poses several challenges not encountered in the corresponding Euclidean setting. These include the fact that the velocity vector should be tangent to the given surface and the possible presence of degenerate modes (Killing fields) in the solution. We analyze a surface finite element method which provides solutions to these challenges. We consider an interior penalty method based on the well-known Brezzi-Dougl… Show more

“…Beyond biological sciences, fluid equations on surfaces appear in the literature on modeling of foams, emulsions and liquid crystals; see, e.g., [42,43,13,6,35,26]. Despite the apparent practical and mathematical relevance, such systems have received little attention from the scientific computing community until the very recent series of publications [27,20,38,39,12,30,34,26,15,4,21,33,5,23] that evidences a strongly growing interest in the development and analysis of numerical methods for fluid equations posed on surfaces.…”

“…In [12], instead, surface Taylor-Hood elements are used and combined with a Lagrange multiplier method to satisfy the tangentiality constraint. Divergence-free DG and H(div)-conforming finite element methods for the surface Stokes problem were recently introduced in [23,4]. These methods enforce the tangentiality condition strongly.…”

“…These equations are also studied as an interesting mathematical problem in its own right in, e.g., [13,45,44,2,24,1,21]. Recently there has been a strong increase in research on numerical simulation methods for surface (Navier-)Stokes equations, e.g., [28,5,38,37,39,15,29,32,6,31,22]. By far most of these and other papers on numerical methods for surface (Navier-)Stokes equations these equations are treated in the primitive velocity and pressure variables.…”
