DMSwarmSetPointCoordinatesCellwise#

Insert point coordinates (defined over the reference cell) within each cell

Synopsis#

#include "petscdmswarm.h"   
PetscErrorCode DMSwarmSetPointCoordinatesCellwise(DM dm, PetscInt npoints, PetscReal xi[])

Not Collective

Input Parameters#

dm - the DMSWARM
npoints - the number of points to insert in each cell
xi - the coordinates (defined in the local coordinate system for each cell) to insert

Notes#

The method will reset any previous defined points within the DMSWARM. Only supported for DMPLEX. If you are using a DMDA it is recommended to either use DMSwarmInsertPointsUsingCellDM(), or extract and set the coordinates yourself the following code

    PetscReal  *coor;
    const char *coordname;
    DMSwarmGetCoordinateField(dm, &coordname);
    DMSwarmGetField(dm,coordname,NULL,NULL,(void**)&coor);
    // user code to define the coordinates here
    DMSwarmRestoreField(dm,coordname,NULL,NULL,(void**)&coor);
