# PETSCDUALSPACEBDM

“bdm” - A `PetscDualSpace` object that encapsulates a dual space for Brezzi-Douglas-Marini elements

## Note

This type is a constructor alias of `PETSCDUALSPACELAGRANGE`. During `PetscDualSpaceSetUp()`, the correct value of `PetscDualSpaceSetFormDegree()` is set for H-div conforming spaces. The type of the dual space is then changed to to `PETSCDUALSPACELAGRANGE`.
