#include "petscvec.h" PetscErrorCode VecMPISetGhost(Vec vv,PetscInt nghost,const PetscInt ghosts[])Collective on Vec Many br
vv | - the MPI vector Many br | |
nghost | - number of local ghost points Many br | |
ghosts | - global indices of ghost points, these do not need to be in increasing order (sorted) Many br |
This also automatically sets the ISLocalToGlobalMapping() for this vector. Many br
You must call this AFTER you have set the type of the vector (with VecSetType()) and the size (with VecSetSizes()). Many br
