Get the j internal local ghost box boundary position for the i sub-domain of the local processor.
- Note
- For the sub-domain i intersected with the sub-domain j enlarged, the associated external ghost box is located in getLocalIGhostBox(j,k) with getLocalIGhostSub(j,k) == i
To get k use getLocalIGhostE

- getLocalIGhostE
Some of the intersection boxes has special position, because they are at the boundary, this function return their position at the border

where X is the local processor rank
- Parameters
-
| output | directory where to write the files |
| p_id | id of the local processor |
- Returns
