[petsc-users] Setting Ghosted Boundary Values

[David Scott]

I wish to set boundary values in a structured grid. How do I do this if 
I am using DMDA_BOUNDARY_GHOSTED? I thought that I should set the 
boundary values in the function specified by a call to DMSetInitialGuess 
but it appears to be passed a global vector.

I would prefer any example code to be in Fortran but that is not essential.
