Pressure-robustness by commuting interpolation operators for Stokes discretizations with continuous pressures

Common finite element discretizations for the incompressible Stokes equations with a continuous pressure approximation -- the MINI element, the Taylor--Hood element, or stabilized equal-order elements -- are not pressure-robust: the velocity error is polluted by the pressure best-approximation error, multiplied by the...

A mass-conserving stress-yielding formulation for the Stokes equation with exact stress symmetry

We introduce a new finite element discretization for a mixed formulation of the two-dimensional incompressible Stokes equations with symmetric viscous stresses. The method is based on a mass-conserving stress-yielding formulation (Gopalakrishnan, Lederer, Sch\"oberl; A mass conserving mixed stress formulation for the S...
