# DMStagStencilLocation
enumerated type denoting a location relative to an element in a `DMSTAG` grid 
## Synopsis
```
typedef enum {
  DMSTAG_NULL_LOCATION = 0,
  DMSTAG_BACK_DOWN_LEFT,
  DMSTAG_BACK_DOWN,
  DMSTAG_BACK_DOWN_RIGHT,
  DMSTAG_BACK_LEFT,
  DMSTAG_BACK,
  DMSTAG_BACK_RIGHT,
  DMSTAG_BACK_UP_LEFT,
  DMSTAG_BACK_UP,
  DMSTAG_BACK_UP_RIGHT,
  DMSTAG_DOWN_LEFT,
  DMSTAG_DOWN,
  DMSTAG_DOWN_RIGHT,
  DMSTAG_LEFT,
  DMSTAG_ELEMENT,
  DMSTAG_RIGHT,
  DMSTAG_UP_LEFT,
  DMSTAG_UP,
  DMSTAG_UP_RIGHT,
  DMSTAG_FRONT_DOWN_LEFT,
  DMSTAG_FRONT_DOWN,
  DMSTAG_FRONT_DOWN_RIGHT,
  DMSTAG_FRONT_LEFT,
  DMSTAG_FRONT,
  DMSTAG_FRONT_RIGHT,
  DMSTAG_FRONT_UP_LEFT,
  DMSTAG_FRONT_UP,
  DMSTAG_FRONT_UP_RIGHT
} DMStagStencilLocation;
```
The interpretation of these values is dimension-dependent.




## Developer Note
The order of the enum entries is significant, as it corresponds to the canonical numbering
of DOFs, and the fact that the numbering starts at 0 may also be used by the implementation.
