#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 PetscLayoutCreate(MPI_Comm,PetscLayout *); PetscLayoutSetBlockSize(PetscLayout,1); PetscLayoutSetSize(PetscLayout,n) or PetscLayoutSetLocalSize(PetscLayout,N); PetscLayoutSetUp(PetscLayout); PetscLayoutGetSize(PetscLayout,PetscInt *); or PetscLayoutGetLocalSize(PetscLayout,PetscInt *;) PetscLayoutDestroy(PetscLayout);
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.
