Hi, If you look at the documentation https://www.dealii.org/developer/doxygen/deal.II/classFE__Enriched.html#ada373a36db9791fa6e6440987e8ce258 then the constructor takes a pointer to the function, not the function itself. So you need to create your object Enrichment<dim>() and then pass a pointer to it. Obviously, it has to be alive while the class is being used.
