Dear developers,
I was reading the presentation on CILAMCE 2014 and there it is mentioned
that for JFNK methods one should look at MOOSE (which is great) but I'm
interested in using it on LibMesh alone.
Iis not FEMSystem using PETSc SNES interface ? Would not only be the case
of setting the proper command line arguments ?? from MOOSE code I see
something like these:
[Executioner] type = Steady solve_type = 'PJFNK' preconditioner = 'ILU'#
petsc_options = '-snes_mf_operator'# petsc_options_iname = '-pc_type
-pc_hypre_type'# petsc_options_value = 'hypre boomeramg'[]
MultiMooseEnumgetCommonPetscFlags(){ return MultiMooseEnum(
"-dm_moose_print_embedding
-dm_view -ksp_converged_reason -ksp_gmres_modifiedgramschmidt " "-ksp_monitor
-ksp_monitor_snes_lg-snes_ksp_ew -ksp_snes_ew -snes_converged_reason "
"-snes_ksp
-snes_ksp_ew -snes_linesearch_monitor -snes_mf -snes_mf_operator
-snes_monitor " "-snes_test_display -snes_view -snew_ksp_ew", "", true);}
Can I just use "-snes_ksp -snes_ksp_ew -snes_mf -snes_mf_operator" ?
