Thank you for your answer. When I am looping through the DoFs of the small cell, is there a way to access the DoF index associated with the large cell?
In other words, can I know which DoFs are constrained with another DoF and the index of the latter? I think AffineConstraint probably uses this, but I cannot find it.
