# DMSwarmInsertPointsUsingCellDM
Insert point coordinates within each cell 
## Synopsis
```
#include "petscdmswarm.h"   
PETSC_EXTERN PetscErrorCode DMSwarmInsertPointsUsingCellDM(DM dm, DMSwarmPICLayoutType layout_type, PetscInt fill_param)
```
Not Collective


## Input parameters

- ***dm -*** the `DMSWARM`
- ***layout_type -*** method used to fill each cell with the cell `DM`
- ***fill_param -*** parameter controlling how many points per cell are added (the meaning of this parameter is dependent on the layout type)





## Notes
The insert method will reset any previous defined points within the `DMSWARM`.

When using a `DMDA` both 2D and 3D are supported for all layout types provided you are using `DMDA_ELEMENT_Q1`.


## When using a `DMPLEX` the following case are supported
```none
   (i) DMSWARMPIC_LAYOUT_REGULAR: 2D (triangle),
   (ii) DMSWARMPIC_LAYOUT_GAUSS: 2D and 3D provided the cell is a tri/tet or a quad/hex,
   (iii) DMSWARMPIC_LAYOUT_SUBDIVISION: 2D and 3D for quad/hex and 2D tri.
```
