=== Mixed Formulation for Poisson Equation ===
In this example the poisson equation is solved with a mixed approach: the stable FE space obtained using Brezzi-Douglas-Marini polynomial of order 1 and Dicontinuos element of order 0 is used.
In this example the Poisson equation is solved with a '''mixed approach''': the stable FE space obtained using Brezzi-Douglas-Marini polynomial of order 1 and Dicontinuos element of order 0 is used.
