Set point coordinates in a DMSwarm from a user defined list


#include "petscdmswarm.h"   
PETSC_EXTERN PetscErrorCode DMSwarmSetPointCoordinates(DM dm, PetscInt npoints, PetscReal coor[], PetscBool redundant, InsertMode mode)

Collective on dm

Input parameters#

  • dm - the DMSwarm

  • npoints - the number of points to insert

  • coor - the coordinate values

  • redundant - if set to PETSC_TRUE, it is assumed that npoints and coor[] are only valid on rank 0 and should be broadcast to other ranks

  • mode - indicates whether to append points to the swarm (ADD_VALUES), or over-ride existing points (INSERT_VALUES)


If the user has specified redundant = PETSC_FALSE, the cell DM will attempt to locate the coordinates provided by coor[] within its sub-domain. If they any values within coor[] are not located in the sub-domain, they will be ignored and will not get added to the DMSwarm.
