Hi,
I am trying to set up a fieldsplit preconditioner for my Cahn Hilliard solver
and I get the following error,
[0]PETSC ERROR: --------------------- Error Message
------------------------------------[0]PETSC ERROR: Petsc has generated
inconsistent data![0]PETSC ERROR: Unhandled case, must have at least two
fields, not 0![0]PETSC ERROR:
------------------------------------------------------------------------
These are the options that I am using, -ch_solve is just a prefix.
-ch_solve_pc_type fieldsplit-ch_solve_pc_fieldsplit_type
schur-ch_solve_fieldsplit_block_size 2-ch_solve_fieldsplit_0_field
1-ch_solve_fieldsplit_1_field 0-ch_solve_fieldsplit_0_ksp_type cg
-ch_solve_fieldsplit_0_pc_type hypre-ch_solve_fieldsplit_0_pc_type_hypre
boomeramg -ch_solve_fieldsplit_1_ksp_type cg-ch_solve_fieldsplit_1_pc_type
hypre -ch_solve_fieldsplit_1_pc_type_hypre boomeramg
Any ideas?
Thanks,Subramanya
