Next, the three different operation cycles of the Multigrid solver are commented: V, W and F. The figure below will be used as reference for the explanation of the different cycles of the Multigrid method.
(a) Level 0
(b) Level 1
(c) Level 2
(d) Level 3
Figure 10.2.1 – Examples with the different refine levels applied in the Multigrid method. (a) Level 0 (original mesh). (b) Level 01. (c) Level 02. (d) Level 03.
