Figure 11From: Accurate and efficient numerical solutions for elliptic obstacle problems Plots of the error ( \(\pmb{u_{h}-u^{*}}\) ) at the \(\pmb{50\times 50}\) resolution for the linear obstacle problem with \(\pmb{\varphi =\varphi _{2}}\) . (a) by the PDL1P, (b) by the obstacle SOR, and (c) by the obstacle SOR+PP.Back to article page
