DMStagCreateCompatibleDMStag#

create a compatible DMSTAG with different dof/stratum

Synopsis#

Collective

Input Parameters#

  • dm - the DMSTAG object

  • dof0 - number of dof on the first stratum in the new DMSTAG

  • dof1 - number of dof on the second stratum in the new DMSTAG

  • dof2 - number of dof on the third stratum in the new DMSTAG

  • dof3 - number of dof on the fourth stratum in the new DMSTAG

Output Parameter#

  • 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.
