PetscErrorCode PetscSectionCreate(MPI_Comm comm, PetscSection *s)
Collective on MPI_Comm

Input Parameters

comm - the MPI communicator
s - pointer to the section

Notes: Typical calling sequence PetscSectionCreate(MPI_Comm,PetscSection *); 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.
