Except possibly for unifrm, the parameters in this
section are probably not useful to most users.
- logical unifrm
- If true, use a uniform refinement
of the grid instead of the adaptive refinement. Default: false
- real mgfreq
- Determines how often to switch from
the refinement phase to the solution phase. Refinement continues
until the number of vertices has been increased by a factor of
mgfreq. Must be greater than 1. Default: 2.
- integer nu1 and nu2
- The number of (half)
red-black Gauss-Seidel iterations to perform before ( nu1)
and after ( nu2) coarse grid correction.
Default: nu1=1 and nu2=2
- integer ncyc
- The number of multigrid cycles in
each solution phase. Default: 1
