[petsc-users] What's the point of DMDA_BOUNDARY_GHOSTED?

[Abraham Taicher]

Hi,

I'm trying to add a Dirichlet boundary condition to my finite element
code.  I want the vector with the boundary data to split across
processors.  I have a rectangular grid so I could just make 4 different
1D DA's and split them up according to the way the 2D DA is split.  Is
that what DMDA_BOUNDARY_GHOSTED is for?  If not, what is it for?

thanks,
