DMSwarmSetPointCoordinatesCellwise#

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

Synopsis#

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

Not collective

Input parameters#

  • dm - the DMSwarm

  • celldm - the cell DM

  • 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;

DMSwarmGetField(dm,DMSwarmPICField_coor,NULL,NULL,(void**)&coor);

// user code to define the coordinates here

DMSwarmRestoreField(dm,DMSwarmPICField_coor,NULL,NULL,(void**)&coor);
