A Nested Dissection ordering algorithm is adopted into the ICCG iterative solver, which can improve the convergence rate of ICCG method in some cases. The ordering effects on the FE meshes are investigated with the convergence rate variation. It turns out that the ordering in the FE meshes has little effect against the acceleration factor in practical use.
