Thanks for looking into this. This looks like we disabled these functions back in the day when computing boundary integrals in 1d did not work. I think this ought to work now. What happens if you just remove these 4 functions from the file, recompile the deal.II library, and test whether the result works for your code?

I question all of the asserts in this file: https://github.com/dealii/dealii/blob/master/source/numerics/vector_tools_rhs.cc My particular case is the one on line 36, for dim = 1 and spacedim = 1. Thanks for looking into this.

I noticed that the code in the existing template should work correctly without any changes. So instead I simply copied and renamed the template, without the implementation asserting impossibility in 1D ( Assert(false, ExcImpossibleInDim(1)); ). My first test ran exactly as expected. deal.II often asserts that something doesn't make sense or is impossible in a certain dimension. Sometimes I agree and sometimes I don't. This is the first time that it's just seemed completely wrong to me. What am I missing? Quite possibly nothing -- we may simply be wrong. Can you point out the file and line where the offending Assert is located?
