Figure 3.

Plot of the normalized L_∞ error (maximum deviation from analytical solution) vs time in the mean (a) and variance (b) for varying ensemble sizes for both DFSP (τ_D=0.1 s) and ISSA (voxel size of 0.06 μm) for an ensemble size of 10³ trajectories. The error increases with time (as expected for a discretized solution) at the same rate for both DFSP and ISSA. Additionally, the error decreases (to the discretization error limit) with increasing ensemble size at the same rate for DFSP and ISSA.
