Up: One-Shot Multigrid Methods
Previous: Infinite Dimensional Design Space
As in any efficient multigrid implementation, it is recommended to
use the full multigrid method. This means to start solving the problem
on coarse grids, and using these solutions as initial approximations for the next
finer level. This process continues until it reaches
the finest level where the solution of the problem is required. The order
of interpolation has to be chosen in an appropriate way, Brandt .
