TY - GEN A1 - Schneider, René A1 - Wachsmuth, Gerd T1 - Achieving optimal convergence order for FEM in control constrained optimal control problems T2 - Proceedings in Applied Mathematics and Mechanics (PAMM) N2 - We propose a new heuristic approach to overcome convergence order restrictions implied by the low regularity of the optimal control due to the activity interface of control constraints. Aligning the mesh with the interface yields an improved approximation of the control. Utility of the approach is demonstrated by numerical experiments.
