# 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 on DM

### 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
