DMSwarmVectorDefineFields

Sets the fields from which to define a Vec object when DMCreateLocalVector(), or DMCreateGlobalVector() is called

Synopsis

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

Collective, No Fortran support

Input Parameters

• dm - a DMSWARM

• Nf - the number of fields

• fieldnames - the textual name given to each registered field

Notes

Each field with name in fieldnames must be defined as having a data type of PetscScalar.

This function must be called prior to calling DMCreateLocalVector(), DMCreateGlobalVector(). Multiple calls to DMSwarmVectorDefineField() are permitted.
