Hi All,

I need some help with the following error:

[59]PETSC ERROR: --------------------- Error Message

The code does not break after the error!
Any idea of what should I check???

I'm using multigrid with the following options:
-scr_ksp_max_it 300
-scr_ksp_type  bcgs
-scr_ksp_rtol 3.0e-3
-scr_ksp_monitor
-scr_ksp_converged_reason
-Q22_pc_type uwscale
-A11_ksp_rtol 3.0e-4
-A11_ksp_type bcgs
-A11_pc_mg_cycle_type v
-no_scale
-no_remove_nullspace
-A11_pc_mg_log
-A11_pc_mg_multiplicative_cycles 1
-A11_pc_mg_smoothup 1
-A11_pc_mg_smoothdown 1
-pc_mg_different_smoothers
-mg_levels_down_ksp_type cg
-mg_levels_down_pc_type bjacobi
-mg_coarse_ksp_type cg
-mg_coarse_ksp_max_it 100
-mg_coarse_ksp_rtol 3.0e-4
-mg_coarse_pc_type bjacobi
-mg_coarse_sub_pc_type cholesky
-mat_schur_sub_monitor


Thanks in advance,
