On the divergence constraint in mixed finite element methods for incompressible flows

V John, A Linke, C Merdon, M Neilan, LG Rebholz - SIAM review, 2017 - SIAM
The divergence constraint of the incompressible Navier--Stokes equations is revisited in the
mixed finite element framework. While many stable and convergent mixed elements have …

Inf-sup stable finite elements on barycentric refinements producing divergence--free approximations in arbitrary dimensions

J Guzmán, M Neilan - SIAM Journal on Numerical Analysis, 2018 - SIAM
We construct several stable finite element pairs for the Stokes problem on barycentric
refinements in arbitrary dimensions. A key feature of the spaces is that the divergence maps …
