The following picture displays a V-Cycle of the multigrid method. Each box represents one of the algorithmic components of a multigrid algorithm. The unbroken channels show how data is passed through the algorithm.
This algorithm is applied to an example problem. The boxes labeled smooth in the picture are active. By clicking on them, information about the status of the algorithm at this stage is displayed (graphically). Mosaic users can use the middle mouse button to obtain the pictures in separate windows.
