Figure 6From: Convergence of a linearly extrapolated BDF2 finite element scheme for viscoelastic fluid flow Vertical velocity \(\pmb{u_{2}}\) near reentrant corner ( \(\pmb{x=4.0625}\) ). The mark ‘o’ indicates results for the steady problem and ‘+’ indicates results for the time-dependent problem at final time \(t=6.31\) with time step \(\triangle t=0.01\) and \((P_{1}b,P_{1},P_{1}dc)\) element.Back to article page
