<br>
Is it valid to have a DMDA with one of the dimensions of size 1. I was<br>
hoping to avoid having to write explicit logic to handle the case that I<br>
am working on a 2D rather than a 3D image for my current application. <br>
Unfortunately when I try to construct such a DMDA I get an error:<br>
<br>
[0]PETSC ERROR: --------------------- Error Message<br>
--------------------------------------------------------------<br>
[0]PETSC ERROR: Overflow in integer operation:<br>
[0]PETSC ERROR: Mesh of 10 by 10 by 1 (dof) is too large for 32 bit indices<br>
<br>
Is there a workaround other than "write everything twice"?<br>
<br>
Thanks<br>
<br>
