Figure 16From: Parallel solutions of static Hamilton-Jacobi equations for simulations of geological foldsTwo neighbouring subdomains, without and with ghost nodes, top and lower illustrations. Ghost nodes are coloured in green. Columns of nodes that exist in both subdomains have been marked with waves or stripes. Arrows show the direction in which nodal values are copied between the subdomains. Notice that two layers of nodes are synchronised between subdomains.Back to article page
