## Abstract Consider the advection–diffusion equation: u~1~ + au~x1~ − vδu = 0 in ℝ^n^ × ℝ^+^ with initial data u^0^; the Support of u^0^ is contained in ℝ(x~1~ < 0) and a: ℝ^n^ → ℝ is positive. In order to approximate the full space solution by the solution of a problem in ℝ × ℝ^+^, we propose the

Control advection diffusion problems are formulated via variational inequalities and effective upwind finite element approximations are studied. The method of local subdifferentials is applied to model and dualize control constraints, as well as to produce global primal and mixed variational formula
