[petsc-users] Output of periodic DM

Dear community,

I create a 1D uniform mesh (3 cells) using DMDA with periodic boundary like this:

x --- x --- x ---

0      1      2

When I output with HDF5 viewer, the solutions "0, 1, 2" are written to the file.

Because I want to do the visualization, I wonder is it possible to write the solutions "0, 1, 2, 0" with another point like

x --- x --- x --- x

0      1      2      0

I hope there is some way to work also in 2D and 3D.

Thank you in advance for any help!
