Variables | |
| double | oomph::HypreHelpers::AMG_strength =0.25 |
| Default for AMG strength (0.25 recommended for 2D problems; larger (0.5-0.75, say) for 3D. More... | |
| unsigned | oomph::HypreHelpers::AMG_coarsening =6 |
| Default AMG coarsening strategy. Coarsening types include: 0 = CLJP (parallel coarsening using independent sets) 1 = classical RS with no boundary treatment (not recommended in parallel) 3 = modified RS with 3rd pass to add C points on the boundaries 6 = Falgout (uses 1 then CLJP using interior coarse points as first independent set) 8 = PMIS (parallel coarsening using independent sets - lower complexities than 0, maybe also slower convergence) 10= HMIS (one pass RS on each processor then PMIS on interior coarse points as first independent set) 11= One pass RS on each processor (not recommended) More... | |
| double | oomph::HypreHelpers::AMG_truncation =0.0 |
| AMG interpolation truncation factor. More... | |
