UMIST Stabilised Vs Stable Mixed Methods


The accuracy of low-order mixed nite element methods for the incompressible (Navier-)Stokes equations is investigated in this work. Some numerical experiments suggest that the lowest-order stabilised P1{P0 method (linear velocity, constant pressure) is more eecient than the alternative a-priori stable non-conforming Crouzeix-Raviart (P?1{P0) approach. The relative accuracy of stabilised P1{P0 and P1{P1 (linear velocity, continuous linear pressure) is also assessed herein.
