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
