+
+------------------------------------------------
+Efficient projection on DG or Quadrature spaces
+------------------------------------------------
+
+
+For projecting a Function on a DG or Quadrature space, that is a space with no coupling between elements, the projection can be performed element-wise. For this purpose, using the LocalSolver is much  faster than performing a global projection::
+
+ metadata={"quadrature_degree": deg}
+ def local_project(v,V):
+     dv = TrialFunction(V)
+     v_ = TestFunction(V)
+     a_proj = inner(dv,v_)*dx(metadata=metadata)
+     b_proj = inner(v,v_)*dx(metadata=metadata)
+     solver = LocalSolver(a_proj,b_proj)
+     solver.factorize()
+     u = Function(V)
+     solver.solve_local_rhs(u)
+     return u
+
+Local factorizations can be cached if projection is performed many times.
