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);
