DAGetCorners
Returns the global (x,y,z) indices of the lower left corner of the local region, excluding ghost points.
Synopsis
int DAGetCorners(DA da,int *x,int *y,int *z,int *m, int *n, int *p)
Not
Collective
Input Parameter
da -the distributed array
Output Parameters
x,y,z | - the corner indices (where y and z are optional; these are used
for 2D and 3D problems)
|
m,n,p | - widths in the corresponding directions (where n and p are optional;
these are used for 2D and 3D problems)
|
Note
The corner information is independent of the number of degrees
offreedom per node set with the DACreateXX() routine. Thus the x, y, z,
andm, n, p can be thought of as coordinates on a logical grid, where
eachgrid point has (potentially) several degrees of freedom.
Any of y, z, n, and p can be passed in as PETSC_NULL if not needed.
Keywords
distributed array, get, corners, nodes, local indices
