DMStagCreateCompatibleDMStag
create a compatible DMStag with different dof/stratum
Synopsis
PetscErrorCode DMStagCreateCompatibleDMStag(DM dm,PetscInt dof0,PetscInt dof1,PetscInt dof2,PetscInt dof3,DM *newdm)
Collective
Input Parameters
| dm | - the DMStag object
|
| dof0,dof1,dof2,dof3 | - number of dof on each stratum in the new DMStag
|
Output Parameters
newdm -the new, compatible DMStag
Notes
Dof supplied for strata too big for the dimension are ignored; these may be set to 0.
For example, for a 2-dimensional DMStag, dof2 sets the number of dof per element,
and dof3 is unused. For a 3-dimensional DMStag, dof3 sets the number of dof per element.
In contrast to DMDACreateCompatibleDMDA(), coordinates are not reused.
