I am using MINRES with GAMG and have supplied various
options<br>
<br>
#PETSc Option Table entries:<br>
-ksp_max_it 500<br>
-ksp_monitor_true_residual<br>
-log_summary<br>
-mg_levels_ksp_max_it 2<br>
-mg_levels_ksp_type chebyshev<br>
-mg_levels_pc_type sor<br>
-options_left<br>
-pc_gamg_agg_nsmooths 1<br>
-pc_gamg_threshold 0.03<br>
-pc_gamg_type agg<br>
-pc_gamg_verbose 7<br>
-pc_mg_monitor<br>
#End of PETSc Option Table entries<br>
There is one unused database option. It is:<br>
Option left: name:-pc_mg_monitor (no value)<br>
<br>
Does this mean that I should have supplied an integer
value with -pc_mg_monitor or is it not applicable in this
case? If I should have supplied a value what is the
allowed range?<br>
<br>
Thanks in advance,<br>
<br>
