Thanks @peterrum . Taking as a reference step-60, we'd like to have a version of `NonMatching::create_coupling_mass_matrix()` which computes exactly the integrals on polyhedra arising from intersections (In that case, the...

@bangerth I have local working and tested versions for all mixed dimensions now, but we wanted to make sure to have a cleaner interface before adding these coupling terms, so...

Hi, I'd like to share here what we did so far to assemble interface terms with different intrinsic dimensions in the context of immersed methods. Unfortunately I am not a...

I confirm that this patch fixes my issue! Thanks a lot @sloriot

Thanks! > Quick question, how did you generate the coarse mesh of the piston ? It's a nice looking unstructured hex mesh. I started with a CAD model of a...

Thanks for reviewing — I’ve pushed most of the required changes. The only part I’m still uncertain about is the assumption regarding the number of components in the (vector) point...

The test `fe_coupling_02.debug` fails because the following assertion is not satisfied https://github.com/dealii/dealii/blob/976d4139ab1e734118db4c69d962ef2f8fb0c22d/include/deal.II/fe/fe_coupling_values.h#L1515-L1516 How would you loop (within this interface) over DoF indices if `DoFCouplingType::independent` is selected?

@kronbichler Sure, maybe #15521 could be a solution. Moreover, since 8 of the 10 most expensive tests are CGAL-related, I will also try to lower those timings.

As a minor remark, to maintain consistency with other linear algebra classes, local-to-global operations should also be delegated to the `AffineConstraints` class. https://github.com/dealii/dealii/blob/14c43b2c2e048922cb9117f1a4a0f30754af24f8/tests/psblas/test_Solver.cc#L124-L129

I was experimenting with my GitHub settings earlier, and that unintentionally triggered the Copilot review. Please ignore it. The test failures were primarily due to tests assuming they were working...
