DMSwarmSetPointsUniformCoordinates#

Set point coordinates in a DMSWARM on a regular (ijk) grid

Synopsis#

#include "petscdmswarm.h"   
PETSC_EXTERN PetscErrorCode DMSwarmSetPointsUniformCoordinates(DM dm, PetscReal min[], PetscReal max[], PetscInt npoints[], InsertMode mode)

Collective

Input Parameters#

  • dm - the DMSWARM

  • min - minimum coordinate values in the x, y, z directions (array of length dim)

  • max - maximum coordinate values in the x, y, z directions (array of length dim)

  • npoints - number of points in each spatial direction (array of length dim)

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

Notes#

When using mode = INSERT_VALUES, this method will reset the number of particles in the DMSWARM to be npoints[0]*npoints[1] (2D) or npoints[0]*npoints[1]*npoints[2] (3D). When using mode = ADD_VALUES, new points will be appended to any already existing in the DMSWARM
