Hi @adamqc, do you observe similar scaling with AMG (without LOR), e.g. in ex0p or ex1p? In our experience, the AMG setup scales better than what you report (though still...

@v-dobrev @tzanio, is this ready for next?

One way of doing this is to use the idea in DG of a numerical flux. Let $V$ be the scalar DG space, and $W = [V]^d$ be the vector-valued...

Hi @Rickbude, First some general comments/questions about approximating the gradient of a DG function that does not necessarily come from a DG discretization of the Laplacian: Does the method you...

FWIW, $p=0$ with IPDG will not generally be convergent (even in $L^2$ norm). You will have to pick the penalty parameter very carefully, and there may be additional restrictions on...

Indeed the $L^2$ order of convergence for IPDG is $\mathcal{O}(h^{p+1})$. The convergence behavior of various DG methods is summarized in this table:  However, note that this result holds for...

Closing for now. @Rickbude, please re-open if you have any other questions.

That part of the code uses some kind of complicated templates and macros. Is it possible to simply skip that file when running SWIG? It's not really user-facing, so we...

What compiler (and version) are you using? It's related to [this](https://stackoverflow.com/a/29618545). We can add a fix/workaround if needed.

Actually I think the problem has to do with the version of the standard library rather than the compiler version: - [clang 14.0 with libstdc++ 5.5.0](https://godbolt.org/z/r3Wdz7s33) ❌ fails - [clang...
