But I am not sure how this would help since PETSC_COMM_WORLD includes all the processors and in all three directions whereas the 1-D data is only the size of Nx points. </div>
<div>This vector is not big at all, I could even create is on one processor. The only concern that I have is </div><div>can I create an *.h5 file using PETSC_COMM_WORLD, dump the data, close the file and then, re-open the file (append mode) with a different viewer created via PETSC_COMM_SELF, and dump the coordinates vector to the end of it? Of course, I only call PETSC_COMM_SELF on processor zero. </div>

Thanks Jed. <div>My solution to that was to create a 1D vector local to for instance processor zero that holds all the coordinates. Then after I dumped all the parallel data to the *.h5 file, I create another viewer on processor zero or PETSC_COMM_SELF and dump that new vector including tHe coordinates to the end of the existing file. </div>
<div>Do you think that should be possible?</div></blockquote><div><br></div></div><div>You should just create a parallel Vec to hold the 1D data. DAGetLocalInfo() tells you all the local sizes.</div><div><br></div><div> Matt</div>

What I need is just to add 3 1-D arrays of (x[Nx]+y[Ny]+z[Nz]) including the grid coordinates to the end of the *.h5 file and then later on, I can use any visualization software to load the data using those coordinates. I am using orthogonal grid, that's why I don't need all the (x,y,z) coordinates for each cell. </blockquote>
