#include "petscvec.h" PetscErrorCode PetscSectionCreate(MPI_Comm comm, PetscSection *s)Collective on MPI_Comm
| comm | - the MPI communicator | |
| s | - pointer to the section | 
Notes: Typical calling sequence
      PetscSectionCreate(MPI_Comm,PetscSection *);
      PetscSectionSetNumFields(PetscSection, numFields);
      PetscSectionSetChart(PetscSection,low,high);
      PetscSectionSetDof(PetscSection,point,numdof);
      PetscSectionSetUp(PetscSection);
      PetscSectionGetOffset(PetscSection,point,PetscInt *);
      PetscSectionDestroy(PetscSection);
The PetscSection object and methods are intended to be used in the PETSc Vec and Mat implementions; it is recommended they not be used in user codes unless you really gain something in their use.
