A fully discrete stabilized finite-element method for the time-dependent Navier–Stokes problem
IMA Journal of Numerical Analysis (2003) 23, 665-691,-0001,():
discrete stabilized finite-element method is presented for the two-dimensional timedependent Navier-Stokes problem. The spatial discretization is based on a finite-element space pair (Xh, Mh) for the approximation of the velocity and the pressure, constructed by using the Q1-P0 quadrilateral element or the P1−P0 triangular element; the time discretization is based on the Euler semi-implicit scheme. It is shown that the proposed fully discrete stabilized finite-element method results in the optimal order error bounds for the velocity and the pressure.
