Collective on DM

Input Parameter

dm -the DM

Output Parameter

c -coordinate vector

Note

This is a borrowed reference, so the user should NOT destroy this vector

Each process has the local and ghost coordinates

For DMDA, in two and three dimensions coordinates are interlaced (x_0,y_0,x_1,y_1,...) and (x_0,y_0,z_0,x_1,y_1,z_1...)

Keywords

distributed array, get, corners, nodes, local indices, coordinates
