[petsc-users] Is use of Mirror Boundary with Box Stencil supported for 2D?

[Macneice, Peter J. (GSFC-6740)]

>From my searching of the documentation, it looks to me as though this combination should work.

However for my modified version of the ex66.c tutorial code, I get the error message below.


Is this really not yet supported?



Regards
