Hi Alex,
I can only give you a very brief answer right now: Using the
AffineConstraints::set_inhomgeneity()
<https://dealii.org/developer/doxygen/deal.II/classAffineConstraints.html#a4f7cb22b3c971599a839fddc988ef92a>
method, you can add the inhomogeneity after constructing the homogeneous
periodic constraints. If you're stuck trying to figure out which global
DoF index you're wanting to set the inhomogeneity for, then there are
some other posts on the group and information in the Wiki that describe
some ways that you can
get that information. If you're still stuck, then let us know and I (or
someone else) can try to give you some more details.
Best,
Jean-Paul

I need to implement periodic boundary constraints with
inhomogeneities. From reading through the documentation and source
code of the library, it seems that to do this I will need to modify
the set_periodicity_constraints function in the
dof_tools_constraints.cc file to also add an inhomogeneity. Is there a
simpler way to do this that I missed that allows me to use the
make_periodicity_constraints() function and then add the inhomogeneity
after calling it?
To give some context, I am solving an elasticity problem that involves
taking a beam, deforming it, and "glueing" together some of the faces
(e.g. to form a ring -- I included an image of this in a previous post
<https://groups.google.com/g/dealii/c/kkYfnir8QVQ/m/Q6G30LFuCAAJ>).
Any thoughts would be greatly appreciated.
Best,
Alex
