Numerical experiments have indicated that both Full Approximate Scheme and Full Approximate-Schwarze Scheme can enhance the computing efficiency, which is affected by three aspects: grid dividing, the number of pre-relaxation sweeps and post-relaxation sweeps, the convergence criteria on the coarse grid.
