Dear Michal, We do not offer convenience access for all data structures on faces yet, so feel free to suggest what you need. That said, for the access of rho and mu on an element, we provide the following access function:

Dear all, I'm trying to use matrix-free with discontinuous Galerkin elements for variable coefficient problem. The face integral require access to value of coefficient. For the cell I've done the following thing: //Vectors of values, stored in object: AlignedVector< VectorizedArray > mu;
