Convergence Analysis of Schwarz Waveform Relaxation for Nonlocal Diffusion Problems

Figure 8

(a) The effects of the discretization parameters and (b) the length of time-interval on the convergence rate of the SWR algorithms using the backward Euler method as the time-integrator in the case of two and eight subdomains. For the BDF2 method, these plots look similar.
