D Frerichs, C Merdon - IMA Journal of Numerical Analysis, 2022 - academic.oup.com
Nondivergence-free discretizations for the incompressible Stokes problem may suffer from a
lack of pressure-robustness characterized by large discretizations errors due to irrotational …

Low regularity error analysis for an H (div)-conforming discontinuous Galerkin approximation of Stokes problem

Galerkin (DG) approximation of the Stokes equations, assuming only minimal regularity on …

An arbitrary order and pointwise divergence-free finite element scheme for the incompressible 3D Navier–Stokes equations

In this paper we discretize the incompressible Navier–Stokes equations in the framework of
finite element exterior calculus. We make use of the Lamb identity to rewrite the equations …

Stabilizing the Scott-Vogelius elements by Guzman-Neilan bubble functions on triangular meshes

S Zhang - Journal of Applied Mathematics and Computing, 2025 - Springer
Abstract The Scott-Vogelius P kP k-1 disc mixed finite element is stable for k≥ 4 if the
underlying triangular mesh is nearly-singular vertex free. The P 2-P 1 disc and P 3-P 2 disc …

A nonconforming pressure-robust finite element method for the Stokes equations on anisotropic meshes

T Apel, V Kempf, A Linke… - IMA Journal of Numerical …, 2022 - academic.oup.com
Most classical finite element schemes for the (Navier–) Stokes equations are neither
pressure-robust, nor are they inf-sup stable on general anisotropic triangulations. A lack of …

Analysis of pressure-robust embedded-hybridized discontinuous Galerkin methods for the Stokes problem under minimal regularity

A Baier-Reinio, S Rhebergen, GN Wells - Journal of Scientific Computing, 2022 - Springer
We present analysis of two lowest-order hybridizable discontinuous Galerkin methods for
the Stokes problem, while making only minimal regularity assumptions on the exact solution …

Pressure-robust error estimate of optimal order for the Stokes equations: domains with re-entrant edges and anisotropic mesh grading

T Apel, V Kempf - Calcolo, 2021 - Springer
The velocity solution of the incompressible Stokes equations is not affected by changes of
the right hand side data in form of gradient fields. Most mixed methods do not replicate this …

Pressure-robustness in the context of optimal control

C Merdon, W Wollner - SIAM Journal on Control and Optimization, 2023 - SIAM
This paper studies the benefits of pressure-robust discretizations in the scope of optimal
control of incompressible flows. Gradient forces that may appear in the data can have a …

A pressure-robust numerical scheme for the Stokes equations based on the WOPSIP DG approach
