[firedrake] Hi everyone,

I would like to try out the Petrov-Galerkin Enrichment Method (Barrenechea et al 2007) for a mixed-poisson/Darcy equation.Here is the link to the paper: http://www.sciencedirect.com/science/article/pii/S0045782507000059 Basically, this method starts with the P1/P0 combination and enriches both velocity and pressure trial functions with multi-scale functions. Is this easily doable within Firedrake? Thanks, Justin
