DMStagStencil#
data structure representing a degree of freedom on a DMSTAG
grid
Synopsis#
typedef struct {
DMStagStencilLocation loc;
PetscInt i, j, k, c;
} DMStagStencil;
Data structure (C struct), analogous to describing a degree of freedom associated with a DMSTAG
object,
in terms of a global element index in each of up to three directions, a “location” as defined by DMStagStencilLocation
,
and a component number. Primarily for use with DMStagMatSetValuesStencil()
(compare with use of MatStencil
with MatSetValuesStencil()
).
Note#
The component (c) field must always be set, even if there is a single component at a given location (in which case c should be set to 0).
