[petsc-users] PetscPartitioner in Fortran

[Jiaoyan Li]

Dear Petsc users:

I am trying to use Petsc APIs for Fortran. One problem that I am facing right now is about the PetscPartitioner, i.e.,

#include “petsc/finclude/petsc.h”
  use petscdmplex

  PetscPartitioner :: part
  PetscErrorCode :: ierr

  Call PetscPartitionerCreate(PETSC_COMM_WORLD, part, ierr)

But, I got the error message as follows:

Is there anyone who may encounter similar problem before? Any suggestions or commends are highly appreciated. Thank you very much.

Best,
