DMSwarmCreateGlobalVectorFromFields

Creates a Vec object sharing the array associated with a given field set

Synopsis

#include "petscdmswarm.h"   
PetscErrorCode DMSwarmCreateGlobalVectorFromFields(DM dm, PetscInt Nf, const char *fieldnames[], Vec *vec)

Collective

Input Parameters

• dm - a DMSWARM

• Nf - the number of fields

• fieldnames - the textual names given to the registered fields

Output Parameter

• vec - the vector

Notes

The vector must be returned using a matching call to DMSwarmDestroyGlobalVectorFromFields().

This vector is copyin-copyout, rather than a direct pointer like DMSwarmCreateGlobalVectorFromField()
