[petsc-users] PC HYPRE BoomerAMG options for nodal

[Bernardo Rocha]

Dear Petsc users,

I would like to use BoomerAMG preconditioner for a system of PDEs, but we
are interested in setting some of BoomerAMG options to use the nodal
systems coarsening.

>From the HYPRE/BoomerAMG manual, I found out that I have to use the
following functions:
HYPRE_BoomerAMGSetNodal
HYPRE_BoomerAMGSetNumFunctions
HYPRE_BoomerAMGSetDofFunc

Looking at the source code (src/ksp/pc/impls/hypre/hypre.c) I've found the
call to the first one, but not for the other two, where I must specify the
ordering of my dofs in my problem.

I would appreciate any help on this.

Best regards,
Bernardo
