[petsc-users] Using PETSc solvers and preconditioners with mfem

[Abdullah Ali Sivas]

Hello,

I want to use PETSc with mfem and I know that mfem people will figure 
out a way to do it in few months. But for now as a temporary solution I 
just thought of converting hypre PARCSR matrices (that is what mfem uses 
as linear solver package) into PETSc MPIAIJ matrices and I have a 
semi-working code with some bugs. Also my code is dauntingly slow and 
seems like not scaling. I have used /MatHYPRE_IJMatrixCopy /from myhp.c 
of PETSc and /hypre_ParCSRMatrixPrintIJ/ from par_csr_matrix.c of hypre 
as starting points. Before starting I checked whether there was anything 
done similar to this, I could not find anything.

My question is, are you aware of such a conversion code (i.e. something 
like /hypre_ParCSRtoPETScMPIAIJ( hypre_ParCSRMatrix *matrix, //Mat *A/)?


Thanks in advance,
Abdullah Ali Sivas
