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