[petsc-users] petsc4py, plotting DA and writing to file

[Amal Alghamdi]

Dear All,

I'm using the DA structure in petsc4py. I'd like to know please what is the
right way to:
plot the DA vector (the global vector).
write the global vector to a file.
Is that each process writes or draws its own part? or I should communicate
all the data to one process? or none of these?!!

Thank you very much
Amal
