Figure 3From: Numerical calculation of protein-ligand binding rates through solution of the Smoluchowski equation using smoothed particle hydrodynamicsComparison of SPH solutions (symbol) to the analytical solution (line) for the Smoluchowski equation subject to the Robin BC on r=R 1 and Dirichlet BC on r=R 2 at steady-state with the relative L 2 errors for different resolutions. Specifically, L 2=0.00914 for Δ x=8Å(green square), L 2=0.00598 for Δ x=4Å(blue circle), and L 2=0.00377 for Δ x=2Å(red triangle).Back to article page
