Dear all:

It seems that if I mesh a cubic domain with “DMDACreate3d” using 8 bricks for discretization and with periodic boundaries, each of the bricks has a different size. In contrast, if I use DM_BOUNDARY_NONE, all 8 bricks have the same size.

I have used this together with the DMSWarm discretization. And as you can see the number of particles per rank is not evenly distributed:
210 420 366 732 420 840 732 1464

Am I missing something?

Thanks,
Miguel
