An Iterative High-Accuracy ADI Method for the 3D Parabolic Equation

Figure 1

The proposed iterative high-accuracy ADI method for 3D-PE. The green circular dots represent the elements that are updated in (14a) at a time. The blue circular dots represent the elements that are updated in (14b) at a time. Step 1 is explicit in the z direction and implicit in the y direction. Step 2 is explicit in the y direction and implicit in the z direction.
