<div dir="ltr">Dear All,<div><br></div><div>I'm using the DA structure in petsc4py. I'd like to know please what is the right way to:</div><div>plot the DA vector (the global vector).</div><div>write the global vector to a file.</div>
<div>Is that each process writes or draws its own part? or I should communicate all the data to one process? or none of these?!!</div><div><br></div><div>Thank you very much</div><div>Amal</div></div>
