547: This function iterates over a manifold, and interpolates the input function/field using the basis provided by the DS in our DM
549: There are several different scenarios:
551: 1) Volumetric mesh with volumetric auxiliary data
553: Here minHeight=0 since we loop over cells.
555: 2) Boundary mesh with boundary auxiliary data
557: Here minHeight=1 since we loop over faces. This normally happens since we hang cells off of our boundary meshes to facilitate computation.
559: 3) Volumetric mesh with boundary auxiliary data
561: Here minHeight=1 and auxbd=PETSC_TRUE since we loop over faces and use data only supported on those faces. This is common when imposing Dirichlet boundary conditions.
563: 4) Volumetric input mesh with boundary output mesh
565: Here we must get a subspace for the input DS
567: The maxHeight is used to support enforcement of constraints in DMForest.
569: If localU is given and not equal to localX, we call DMPlexInsertBoundaryValues() to complete it.
571: If we are using an input field (DM_BC_ESSENTIAL_FIELD or DM_BC_NATURAL_FIELD), we need to evaluate it at all the quadrature points of the dual basis functionals.
572: - We use effectiveHeight to mean the height above our incoming DS. For example, if the DS is for a submesh then the effective height is zero, whereas if the DS
573: is for the volumetric mesh, but we are iterating over a surface, then the effective height is nonzero. When the effective height is nonzero, we need to extract
574: dual spaces for the boundary from our input spaces.
575: - After extracting all quadrature points, we tabulate the input fields and auxiliary fields on them.
577: We check that the #dof(closure(p)) == #dual basis functionals(p) for a representative p in the iteration
579: If we have a label, we iterate over those points. This will probably break the maxHeight functionality since we do not check the height of those points.
