Comparison of conventional FD and improved FD with RPBC for a 1D isotropic diffusion sample with four types of pulse sequences: PGSE-short, PGSE-finite, OGSE-sin and OGSE-cos (for definitions see the first paragraph of section 3.1). Note that results with the conventional FD method are calculated from the whole computational domain and show large errors caused by the edge effect. In contrast, all results with RPBC have errors smaller than 1%, which shows the elimination of the edge effect. The definition of the error is the same as in figure 2.
