How to apply a slope limiter (minmod) to the Discontinuous Galerkin (DG) method?
For people that may have the same question. It was not computationally expensive, since the matrix only had to be calculated once. I also applied the minmod limiter to the solution sol(t)->minmod(...

$H^2-$ conforming finite element on cube
In this paper "MATLAB Implementation of C1 finite elements: Bogner-Fox-Schmit rectangle", they define it as products of Hermite polynomials in 2D, so you can try to generalize this to 3D. It ...
