@bangerth @GrahamBenHarper what about this topic? Are you expecting progress until mid May? If not, please adjust the target milestone.

I also think we should postpone this to after the release. Let me adjust the milestone.

Adjusting to the 9.3 milestone now that we have the temporary solution.

We have `dim=3, n_q_points_1d=2, n_components=3`. That should give us 72 entries in `fe_eval.begin_gradients()` with good data. The fact that the 25th entry is wrong must mean that the function that...

The quadrature stuff is mostly independent indeed. The reason I mention it here is that we should think about that case when we redesign interfaces, in order to avoid going...

Let me start the reply with going back to this one: > The concrete implementation of an operator has to follow an interface, so that `MatrixFreeEvaluator` (holding a pointer to...

> Is the implementation restricted to certain types of finite elements, i.e. does the implementation assume an "isotropic" element in case of vectorial problems, where the different components all have...

> I did not understand which functionality of FiniteElement you are referring to? Or do you mean functionality hidden by RemotePointEvaluation or point_values()? I was thinking about `FiniteElement::convert_generalized_support_point_values_to_dof_values` in the...

Discovered while working on #132.

As a remark, I tested this on the backward facing step and had to fix some minor issues there. Is there any additional test I should run?
