<A NAME="DMBoundaryType"><H1>DMBoundaryType</H1></A>
Describes the choice for fill of ghost cells on physical domain boundaries.
<H3><FONT COLOR="#CC3333">Synopsis</FONT></H3>
<PRE>
typedef enum {DM_BOUNDARY_NONE, DM_BOUNDARY_GHOSTED, DM_BOUNDARY_MIRROR, DM_BOUNDARY_PERIODIC, DM_BOUNDARY_TWIST} <A HREF="../DM/DMBoundaryType.html#DMBoundaryType">DMBoundaryType</A>;
</PRE>
<P>
A boundary may be of type DM_BOUNDARY_NONE (no ghost nodes), DM_BOUNDARY_GHOSTED (ghost vertices/cells
exist but aren't filled, you can put values into them and then apply a stencil that uses those ghost locations),
DM_BOUNDARY_MIRROR (not yet implemented for 3d), DM_BOUNDARY_PERIODIC (ghost vertices/cells filled by the opposite
edge of the domain), or DM_BOUNDARY_TWIST (like periodic, only glued backwards like a Mobius strip).
<P>
Note: This is information for the boundary of the __PHYSICAL__ domain. It has nothing to do with boundaries between
processes, that width is always determined by the stencil width, see <A HREF="../DM/DMDASetStencilWidth.html#DMDASetStencilWidth">DMDASetStencilWidth</A>().
