Hi,

I'm trying to use PETSc with cyclicAMI in OpenFOAM (2206). However, I got the error msg:

solvers/petscSolver.C at line 671.
[147]
FOAM parallel run exiting
[147]

[158]     From void Foam::petscSolver::buildMat(_p_Mat*&, Foam::List<int>&, PetscInt&) const
[158]     in file solvers/petscSolver.C at line 671.

[30] cyclicAMI is not supported

Here's my PETSc config in fvSolution:

solver petsc;

        petsc
        {
            options
            {
                ksp_type  cg;
                ksp_cg_single_reduction  true;
                ksp_norm_type none;

                // With or without hypre
                //#if 0
                mat_type aij;
                pc_type  hypre;
                pc_hypre_type boomeramg;
                pc_hypre_boomeramg_max_iter "1";
                pc_hypre_boomeramg_strong_threshold "0.25";
                pc_hypre_boomeramg_grid_sweeps_up "1";
                pc_hypre_boomeramg_grid_sweeps_down "1";
                pc_hypre_boomeramg_agg_nl "1";
                pc_hypre_boomeramg_agg_num_paths "1";
                pc_hypre_boomeramg_max_levels "25";
                pc_hypre_boomeramg_coarsen_type HMIS;
                pc_hypre_boomeramg_interp_type ext+i;
                pc_hypre_boomeramg_P_max "1";
                pc_hypre_boomeramg_truncfactor "0.3";

So is it supported? I also tried GAMG but the errror is the same.

Checking the source code of the petscFoam module confirms that currently, it doesn't support cyclicAMI
