#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.
