return global element indices of the local region (excluding ghost points)
Synopsis#
Not Collective
Input Parameter#
- dm - the - DMSTAGobject
Output Parameters#
- x - starting element index in first direction 
- y - starting element index in second direction 
- z - starting element index in third direction 
- m - element width in first direction 
- n - element width in second direction 
- p - element width in third direction 
- nExtrax - number of extra partial elements in first direction 
- nExtray - number of extra partial elements in second direction 
- nExtraz - number of extra partial elements in third direction 
Notes#
Arguments corresponding to higher dimensions are ignored for 1D and 2D grids. These arguments may be set to NULL in this case.
The number of extra partial elements is either 1 or 0. The value is 1 on right, top, and front non-periodic domain (“physical”) boundaries, in the x, y, and z directions respectively, and otherwise 0.
