Abstract:
Recently there has been increased interest in a special class of discretizations for incompressible flows, which produce velocity approximations that are independent of how well the pressure can be approximated. For this reason such methods are called pressure-robust. While classical methods like the family of Taylor-Hood finite elements show a locking phenomenon induced by the viscosity parameter of the fluid, meaning that the error of the discrete velocity solution scales with the inverse of t...    »
